If you can, make one of the doors at least 1' tall. I'd use 3 separate doors.

Compressor inside may make for less condensation inside the tank if the garage is heated in winter.

Just a thought: A wash bay probably won't be viable with everything else inside unless it is a complete separated section and sealed off from the rest. And will put moisture on everything.

Heat depends on your resources and frequency of use. Probably not an abundant supply of firewood in OK? Occasional use is probably gas. Daily use might be more like a house and so maybe a heat pump with a back up source; it all becomes about heating efficiency if it is heated all the time.

Consider making it a steeper roof (like 8 over 12) and 1-1/2 stories and put storage, bath, office, etc., upstairs to keep your shop space freed up. Park the compressor under the staircase. Have a lift hole into the storage space that is not right in the middle of a bay.
