In general, after thoroughly sanding the surfaces, I seal all screw heads and imperfections/holes in the plywood (especially along the ends) with a filler/sealer material (DAP, etc.), apply a coat of heavy exterior primer (KILZ or similar), and then apply 2 coats of the desired top coat (semi-gloss is adeqate). As long as exterior grade materials are used, it is not necessary to use a polyurethane finish (plus, this may likely make the surface * too * slippery - it certainly will yellow white surfaces).
