The family has both options - it has made no difference afterwards or even during construction.

Before finish flooring high spots are ground off and low spots filled. OSB products have some water protection - wax on the surface and sealed end cuts.

Not a concern. If you want or need hardwood to run parallel to the joists, upgrade the thickness. This is also a good case for plywood - its less bendy than osb.
