I would start with a a work bench at a comfortable height for sitting on a stool, my knees hurt if I stand too long (flat feet), as well as standing up. I would use a white plastic top on the bench for visibility, and put a 3/4- 1 inch beveled edging all around to prevent little parts from falling into the black holes that lurk just past the edges of work tables.

The only tool I would mount on the bench would be a vise, I would have a separate wheel truing station, parts washing station and separate grinder/polisher.

I would put a pegboard on the wall for specialty bike tools and "most used tools" e.g. 3 way 8/9/10 socket, 3 way allen, screwdriver, pliers etc. I would try to keep it as simple as possible, putting out the tools that I know I will always be using. That whitworth tap for Sturmey Archer axle hubs would not be one of them.

I wrench on cars also and have gotten used to tool boxes with dedicated drawers, e.g., one drawer for different types of pliers, one for hand wrenches, one for sockets etc., so I would put the tool box on a movable cart near the bench. I only color code 10 and 13 mm wrenches and sockets. Mine are always (alright, usually) in order so I just count up or down for the one I need.

A sink would be nice and of course, a killer sound system and a mini fridge are absolutely necessary.

Have fun, I envy you!
