The tiles are more costly, but they install in a flash. The painted floors are cheap, but takes time to prep before applying. Cleanup is easier on the painted floors. Desk chairs roll better on painted floors. You can bolt stuff down on a painted floor. If they get scratched, you can touch it up. So, I would go painted floor. My garage floor isn't painted. I had zero time when we moved into the house. Everything got staged into the garage. This will be a project for me down the road.
As for pegboard, you can use regular pegboard and paint it with a Metallic rattle can paint. Does metal hooks actually screw with Wi-Fi? I never noticed. They make plastic hooks. Just don't hang anything too heavy on it.
Foam garage door insulation would be nice. If you have the ability to foam your walls, that would be very nice. A portable AC unit is handy, you can keep it at your "desk" side when you work there, then roll it to the "car" side when you're working on the Jeep.
My next garage project is hanging PVC or copper pipes to drop connections for the compressor. I already installed 20+ new 20A outlets.
Have fun! Seems like a really cool idea.
