Two switches but looks like there is space for everything in the top switch?
Anyway, it's tricky to make it nice when you have to use what you have.
But different length patch cables make a big difference. Same color unless it's color coded for some reason.
I suggest the thin patch cables that someone from here recommended to me. They are awesome and a lot thinner than what it looks like. You can fit about three times as many cables in the same space.

And yes, put 19" power strip on the bottom. Something like:

I'd probably forgo the horizontal cable management and go directly from patch panel to switch. Perhaps even move them together. If you have vlans, reconfigure the switch so you cable it neatly.
