Trying to correctly understand core licensing in a vmware environment

Look at the example here, three tiny hosts (I know it's just a theoretical learning example, but it's how people do it) with six CPUs where three would be cheaper and have better performance, and three hosts where two would be cheaper and have better performance.
Look at the cluster size, it's a total of 36 cores. You can do that better and cheaper using two, single socket servers with 18 cores each! If you needed a little extra during a failover, go for two at 20 cores each or whatever.
I'm not that knowledgeable with hardware, including processors and things.. but are you saying that single socket with x number of cores is better/faster than multiple sockets with x number of cores?

So we're at like $35,000 of software licensing at this point... For what? What's the end goal here that justifies the costs? Oh, that's not even considering CALs. That could be many more thousands. And this is every few years without SA.
I'm not sure how you came up with $35,000 here... I calculated that it would be around roughly $3K for core licenses across those three hosts (per every 2 instances of Server 2016).
That $35,000 is a rounded up figure of you'd get Windows Server Licensing with SA for 9 VMs, plus the cost of VMWare, which you already have. I was figuring between $4-$5k per 2 VMs. Cheaper without SA, then it's about $3k per 2 VMs.

We purchased vSphere Essentials Plus 6 back in 2016 for like $5k, which allows for vCenter and up to 6 CPUs. I don't really know anything about licensing per vm with that... I will have to look into it again.vv

All other factors being equal, yes. The same power with fewer cores, fewer sockets, fewer procs is ideal. It's not very often you can get it apples to apples, but you can get pretty close with processors and cores in this range today.
A single 16 core X processor at Y speed is faster than two 8 core X processors at Y speed for nearly all things. This is because it gets all of its memory from a single source and doesn't need to pass as many workloads back and forth between processors. There is overhead to that that you can avoid.
And a single processor of double the cores is generally quite a bit cheaper than two of half as many cores.

ok, this is pretty much what I was assuming.

This is how I got the go ahead to look into Docker. We were looking at datacenter licences for our new IIS project. However, you can have unlimited windows containers on Windows Standard
That's because there isn't another OS, it's just an app encapsulated.
And the benefit to us is that the OS is now no longer the smallest unit of isolation. The original plan has a ton of VMs so that parts of the stack could be updated without affecting other parts, and without any downtime. Basically they were trying to design a modern app stack, but trying to avoid learning new technology, and Windows licencing costs saved the day.

Isn't the bare minimum VMWare cost like $1300 per Cpu socket?
ESXi is free. If you want to run central management it's ~$600 for essentials (Roughly $100 per socket for 3 hosts) or $6000 for essentials plus (Around $1000 per socket, but includes a vCenter license).

Now to make things more complicated, if you didn't want cluster mobility, but only failover, you can move to SA licensing which isn't cheap, but is way cheaper than this. But if you wanted that, the three node cluster doesn't make sense. So based on the example, SA doesn't cover the goals.
So this is the first time I think I've heard of Software Assurance, and I've just looked it up and done a bit of reading. I understood the words that I read, but it's not really clear to me what exactly SA is or how it could help me in this situation... would you mind helping me understand?
SA is a "maintenance plan" for your Microsoft software products that are not SaaS (so MS office, Windows desktop, Windows Server, Exchange, SQL Server, etc.)
Basically, if you buy software the non-SA way, you pay for it and then... that's it. One time cost, and that's all you pay and.. that's all you get. It's very straightforward.
With SA, you get several benefits, but essentially there is one big one that is what SA is really about - you pay a small amount annually and you get upgrade rights. So, as long as you maintain your SA on a product, it changes it from...
Non-SA: "I bought Windows Server 2016!"
to
SA: "I bought Windows Server!"
You no longer care about the "version" that you buy, your SA means you have the right to use any recent version (so right now that's something like 2008 R2, 2012, 2012 R2, 2016, and 2019 in a few weeks.) You can deploy any of them that make sense today, and upgrade anytime that you want. No more "paying for the next version."
You get lots of silly extra like training and "support", but it's all minor. Sometimes certain features like maybe VDI are included with SA only, in those cases it can be a bigger deal.
In the Windows world, SA is often just considered a part of the license cost and most people ignore that there is even another way to buy Windows because it's the cheaper way to keep your Windows running healthy. Paying for each new version is more costly and more complex. But in the extreme small business arena, skipping SA is common and is often a major contributing factor to finding shops with extremely outdated systems because the pain of the full cost for the next upgrade was too much, but SA makes it a small, annual fee every year instead which is way easier to budget for.
So, does that mean if I installed 2008 R2 several years ago, with SA, I can move that server to a 2016 box for free? Otherwise I still don't understand.
Yes. Where "free" = "already paid for SA". So no additional cost.
Note, SA is a subscription. SA is normally sold for 3 year terms, so at this point you would have paid for possibly 2 renewals. Given the price of the SA renewals it would have been cheaper to just not have bought SA and bought 2016 on the new box.

There are vMotion implications on SA for the non-OS bits sometimes (SQL/Exchange, you need it to move a host, otherwise you will need to high water mark license all the hosts).

Our support renewal is something like 3 years. I haven't had to pay $1,000 per year or anything and I was able to upgrade vSphere from 6 to 6.5 and now I can upgrade to 6.7 if I want.

There is a good discount for renewing it for 3 years. It's a relatively cheap fee to keep current.

If you do not have SA, then when you move a virtual instance of Exchange, Skype for Business, SharePoint, or SQL from one physical host to another, the receiving host must already have a license to cover the virtual instance. The license does not travel with the virtual machine.
If you have SA the license can move between hosts (Note this is NOT true for Windows Server licensing, just SQL/Exchange etc).
What I mean for High water mark is The number of OSE's licensed for a server needs to be licensed for the maximum number of servers that run there in all vMotion scenario's (Unless you license a host for Datacenter Edition).

Wait, so if I have a VM running Exchange or SQL, I need to have SA in addition to having licensed the cores of each host server? Sorry, I've only just now learned about SA so I'm still wrapping my head around it.

SA for SQL or Exchange is not the same as SA for Server. SA is separate for ever single piece.

SA for Server is required for license mobility also. That or purchasing for all servers as previously discussed.

If you have SA on your Server 2016 license, you are allowed to move it around between hosts. So you would not need to purchase licenses for all three hosts.

This isn't true. SA provides upgrade benefits for the server OS, but for sub 90 day license mobility (vMotion/DRS) you have to license all hosts in the cluster to the peak consumption they will use.
What SA on server gets you is SPLA/Azure hybrid use so you could move the VM to public cloud.
SA for SQL/Exchange gives you license mobility.
