my ceiling is 12 ft 6 inches and that was just enough clearance to get a paint roller between the top of the lift and the ceiling. anything less and you will not be happy.
horizontal 2x4 screwed into studs then various hooks screwed into 2x4.
So if you want to change configuration later......not a bunch of holes in OSB or whatever your sheeting is.
the problem with PC is taking lug nuts off/on the surface will chip. having tires installed will also chip. how do you "touch up" the chips?
Spray bomb has an almost infinite choice of colors and will last many years if you properly prep the wheels, and you can touch up any chips without much...

It started cracking within a year (the pros predicted that would happen).
My detached garage has 3/4 OSB on the interior walls (2x6 studs on 16 centers).
Why...
I would not use drywall.....too much temp swing in a detached garage unless you plan on keeping it continuously heated and/or cooled for a full season. Drywall joints WILL crack with temp swings. My Son-In-Law just recently insulated and covered the walls with plywood (no joint filler) and...
my recommendation is to find a local dealer that is willing to come to your garage and help you decide what type (2 post or 4 post), load capacity, brand, etc.

I only have half of the equipment from your list in my detached garage.
But I had a 200 AMP service installed by a licensed contractor and I will never have to worry about an "upgrade" down the road.
