Remember when talking door height to understand the difference between door height nad finished opening height from finished floor.
Concrete is going to crack, control the crack with expansion joints.
Concrete finish, real smooth, easy to clean,especially cleaning up spilled oil, but could be slippery when wet.

X2 on the door height. I didn't want any overhead door tracks in mine so I installed a roll up door. Since then I've noticed a farmer that has fold out hangar style doors on his barns. That's the way I would go now. You can build a pretty big door if needed. Provides extra covered working space.
