Many or most hybrids have 135mm rear spacing, which is near standard for MTBs and touring bikes as well. The resulting reduced dish favors a more durable wheel, but this is probably unnecessary for the unloaded, recreational pavement jaunts.

I believe most cyclocross bikes, particularly the competitive models, have 130mm spacing. Wheels for cross bikes seem to be very much like a sturdy road wheel build (32h x2/x3) with similar rims.

Rim width is all over the place.
