Let's say you've got a house full of natural wood trim (polyurethane), and
you really want it semi-gloss white. Would you paint it, or just buy new
preprimed trim? If you paint, do you degloss first, or just put on the
primer and then paint over?

I would paint vs replace trim, if trim is in good condition. Way less
work. I use 409 or Fantastic to degrease the trim. Then apply alcohol
based Zinnzer or Bullseye primer. Follow instructions on primer, to the
letter. Then lightly sand, and finish coat.
For a smooth finish, freer of brush strokes, and lasting quality, I like
to use oil based (alkyd) top coat.

your better off sanding first espically if the poly is glossy
