If you’re still in the planning phase I highly recommend running power and dust collection to the table saw under the floor, much nicer than having drops you have to work around. I did this for TS and planer that sit relatively in the center of my shop.
My ceiling is only 9ft but I have a ceiling outlet for a air filter, and a spring wound power cord.
I have twenty-some 120v outlets around my 18ft x 25ft shop on the walls both at 14” height for stationary tools and at 4ft height for plug access, these are wired on ~4 20A breakers, interleaved so outlets near each other are on different breakers.
I also have dedicated 240v outlets placed on all walls at 14” height for power tools beside the floor 240’s for TS and planer (BS, DC, lathe) with a couple extra should I want to move things around.
My lathe sits near the wall between a window and a corner. This gives me light, and views as well as access to two walls to hang tools on as well as run power, air, and DC from.
Since my back is to the door of my shop I also have a sign outside, and have trained my wife well, to knock before entering and if I haven’t noticed to flash the overhead lightswitch on the wall just inside the door. Being surprised while concentrating on a turning is no fun.
Lastly, just like outlets and clamps, you can never have too much light in a shop; especially as we get older
