What's the difference between oil based and water based polyurethane?
Water based poly has lower odor and dries faster. If oil based poly
does not have any advantages over water based this makes water based
poly a clear choice. Maybe there are finishes that water based poly
cannot be used on or is not recommended?

The same question applies to water based and oil based stains.

Water based will almost always raise the grain and will require special
preparation. Typically you wet the surface and sand again before applying
the water based finish to minimize the wood fuzzing.

Oil has warmer tone, won't make bits of steel wool turn
into rust bloom. Use Scotchbrite for rubbing out.

A better solution is to use Seal Coat first. Much less sanding.

Oddly, I was putting an oil based varnish on Tiger Maple veneer and the
grain raised. Buffing it with steel wool after the first coat solved the
problem.

Besides the obvious of the grain raising with water base poly is the
ambering. Oil base poly ambers while waterbase stays relatively clear.
Not a problem with dark woods but a big problem with light colored
woods like maple and holly if you want to maintain their light color.
