Op this will be way more than you want. Sorry in advance.
People call my elec outlet amount overkill. My shop is designed with the layout that every 8' you could run an entire small shop. At minimum there is two 220s and 4 110 outlets none of either on the same circuit. Roll a big tool or two there, your good. Need a bench and some power hand tools, your good. Combo of those, your fine.
For 110 tool spots i run 12ga romex, 20amp outlets, 20 amp breakers all at 52". Most of my 220 tool spots get at least 10ga romex, 30 amp l6-30r outlets, 30amp breakers, at 24". Breakers are for the wire in your walls not your tools.
I do use gfci 110 outlets. They are the first outlet in the circuit series. For high outlet circuits that first gfci is accessable on floor.
I run cyclones and upright compressors and have 220 outlets high for those. I also run 8ga and 40 amp circuits for the compressor spots.
My cyclone is central line to my woodworking area and most efficient main duct line for the biggest chip makers, jointer, planer, shapers.
Welder spots, in or outside, run a 50amp 6ga setup.
Run lighting circuits so you can split and control where and how much light you want.
I do sub panels on north and south walls. Makes it easier to install. Mine have access for in wall and exterior conduit. Surface mounted with rear access holes.
In each wall area (be it every 4' or 8' ) have multiple circuits of each type. No two tools of same voltage requirement that you use next to each other will tax the same breaker.
Ceiling outlets for tool drops. Also switched outlets up high for things like ambient air cleaners, ceiling fans, etc.
Outlets for garage door openers. I use jackshaft openers so those are high for me.
Cat6 up to a spot for an access point if you have internet out there.
I also wired for speakers and hdmi for video.
Every 8' I have a control multi conductor wire ran in series back to my dc and 3ph rpc area for control stop stations.
Any chance of 3ph rpc. Thats a whole other set of advice.
