It was recommended I sand poly interior trim before painting white. If it's
not flat (i.e. it's typical nook-and-cranny cross section, like most trim
nowadays), how do you go about sanding it?

You should clean the trim to be painted before sanding to make sure
there's no grease or oils that will cause problems with the finish.
Wrap sandpaper around a suitably sized dowel or pencil to sand the
rounded parts, and fold the paper to sand into the sharp corners.
Other than that it's business as usual. You're just scuffing up the
surface to give the paint primer something to bite onto. Use a primer
with high adherence like Benjamin Moore's Fresh start.

You could use a liquid deglosser (aka liquid sandpaper) that is a
really nasty chemical cocktail that will soften the poly and give it
some tooth for the primer. It will also take care of the cleaning
step at the same time. It's nasty stuff so wear a respirator.
