Leaving plywood subfloor exposed
Seals the wood better then just plan primer. Shellac is often use on knoty woods to seal the knots to stop them from bleeding through the primer and paint.
It's not going to have to be perfect, a roller frame with a long handle on it so you can stand up while doing it should be fine, with a 1/2" nap roller cover, might want to also have a 4" brush handy to hit any spots you miss along the baseboards.
Make sure you start in a corner and work your way out to the door way.
