My garage has drywall. I installed FRP Board 4' off the floor to protect the walls. Then I used vinyl wall base board to give the floor/wall junction a clean look. Finally, I caulked all the seems. I can take a garden hose to the 1st 4' up the wall and wash my floor if I want. The FRP protects the wall from dings like the OSB does. It also wipes up really nice.

Few other tips: you can't have too many electrical outlets, install wood backing in known locations where heavy objects will be stored or secured, LED lights!, and a ceiling fan to move air around and assist drying the floor.

Beer fridge, other electrical for future wants (TV, speakers, etc.). It will only cost more money in the future once the walls are up, so run the necessary wire while you have the cheaper chance
