Yes, the person in the shop pointed out to me about the diopter, I didn't even know about it, so I'm sure the Olympus Viewfinder would be fine.
Also worth noting, if you are nearsighted like me, mirrorless is a "look near" system as the LCD is right in front of you, and an SLR is "look far" as you are actually looking at the object off in the distance.

I did find out that the Olympus has a Micro 4/3rds sensor and the Canon 50M an APS-C sensor and since landscapes are going to be a popular choice for images, the larger sensor would be helpful.
I'm confused. What does sensor size have to do with this? Sensor size itself means absolutely nothing. Sensor size is an underlying, indirect (under the hood) factor that determines lens design, cost, quality, etc. But has nothing to do with type of photography, etc. Bigger sensors need bigger lenses to do the same work, so require way more weight and cost in glass to do the same things. So unless you have an unlimited budget, bigger sensors work against you as they make the things that matter harder to do, and only change the things that don't matter.
It is by making the sensors super small that phones are able to compete.

If anything, the larger the sensor, the harder to get glass to handle landscapes. Smaller sensors make everything easier, all other things being equal.

I can only go by what I've read which said that a larger sensor will let in more light which is helpful in low light situations.
Also I read that a the smaller the sensor the more zoomed in an image appears. From what I understood, and if I can paraphrase, If looking at a face a larger sensor will see the eyes, cheeks & chin, but a smaller sensor will only see the nose, hence the image is zoomed in if you like.
If I understand that correctly, a larger sensor would be better for landscape shots.

That's true, but essentially useless info. This is one of those "out of context" pieces that sounds informational, but actually misleads you. you see, the sensor has more surface area to let in more light, but that's never been the primary issue with low light sensitivity. The main problems are glass and aperture. Both of which get worse when the sensor gets bigger. So bigger sensor normally causes low light problems, rather than fixing them.
This is like where they say "If you want ZFS to manage disk alerts, you need to skip hardware RAID" and people think it means you need to skip hardware RAID, but really it means that you don't normally want ZFS to manage the alerts.
This is why looking at "under the hood components" without looking at the full system is misleading. The information you have is true, but you don't have the full picture to see how it is likely to apply to the end result. You are reading out "means" and not looking at the "ends."
This is why many phones with itty bitty sensors have better low light handling than some expensive "big sensor" cameras - because they are able to achieve huge apertures with lots of glass affordably.
What matters for low light photography is your resulting F stop (aperture) combined with the ISO rating of the sensor. That's it. How those numbers are achieved can be from many factors, factors that might be interesting, but not factors you can look at in isolation to figure out how well the system will work.

All kinds of concepts are being mixed together here and attributed to the wrong components of the system. What you are reading is someone talking about problems that would arise if you put a different sized sensor into a camera built for a different sensor size. Of course it's going to be all screwed up because the lenses will be adjusted all wrong. But don't take "the camera will be broken" to lead to advice about how to build a camera.
Think of this in IT terms. Imagine if you want to build a server, and you only read about CPUs. You start ignoring drives, RAM, operating systems, etc. and start looking at CPUs in a vacuum. Pretty soon you read that ARM CPUs are more efficient, or Power CPUs are faster and you build a system with a $1000 CPU, no RAM, a slow hard drive, and expect to install Windows 10 and then find out that the obsession with the CPU was pointless as only AMD64 CPUs will work with Windows, and you glossed over the important components that make the most difference.
It's great to want to learn about how cameras are designed and built, and in doing so you can understand them better. But in order to understand the components, you have to understand the entire camera, and then learn about the sensor, lens, aperture, ISO sensitivity, sensor speed, mirrors, and other components in the context of how they go into building a complete system that works as a whole. Unless you are going to do that, you cannot look at an individual component and make these kinds of observations or your conclusions are going to be, at best, random, and at worst, backwards.
There is a reason why big sensors are most popular with portraiture and small ones most popular with landscape; but we should never discuss sensors in a vacuum like that because that knowledge on its own will never do us any good.

This of this another way....
Small sensors can handle low light better than some large sensors. And small sensors can handle full 360 degree "as wide as it is possible to be" shots. Given those two facts, which are trivial to prove facts because both are common and can simply be shown, then try to apply your "big sensor for better low light and less zoom" theory. Doesn't make sense, right? The bigger sensor can't go beyond the "perfect" 360 degrees, and you can't argue that they are better for low light if the smaller is better for low light (sometimes.) So it is easily provable that all those conclusions can't be true.
What a big sensor WILL do, is make the camera larger and more expensive. There is no way around that, because you need more glass to handle a bigger sensor, and the glass is the most expensive part of any camera. So the cameras get heavier, and longer. That's a guarantee.
Beyond that, if they zoom more, zoom less, better lowlight, worse low light, better for certain types of things, or not... are not determined by the size of the sensor but rather by the collection of camera design components - almost all of which are in the glass, not the electronics.

Thanks for taking the time write up so much info @scottalanmiller it's greatly appreciated.
The hunt continues & the knowledge increases.
Thanks again.

More or less, look for a camera that is comfy to hold, does the things that you want to do, is the right size and weight, and check the image quality. That's really what matters.

@PhlipElder sweet flower pic! I spent most of a year taking flower pics at my parents house. Totally basic camera though.

Thanks. Unfortunately, a camera kit is out of the question for us right now thus the pursuit of a lens kit for my iPhone X which takes half decent pics ... just a crappy camera app that is nowhere near as good as the Microsoft one was.
My wife's birthday presents for the last three years has been garden roses along with two rose gardens one two years ago and one this year. I love roses. My mother had an amazing rose garden when I was growing up and I have lasting memories of them.
