choices besides UF-B wet damp location not inside conduit
You use individual wires in conduit, not a cable

Pulling cable through conduit is a miserable job -- NM and UF cables use solid wire, making them awful stiff, and the jacket just makes them stiffer and harder to pull still, especially around bends.  Instead, you want to take some single wires rated for wet location service (you can get THHN/THWN-2 dual-rated single conductors basically anywhere building supplies are sold) and pull an appropriate bundle of those through your conduit instead of a cable.

This will make your pull easier then and there because said bundle's less stiff and snag-prone due to not having a jacket; furthermore, you can get stranded THHN/THWN-2 wire in most places, which will make your pull easier still as stranded wire beats solid wire of equal size on flexibility, every time.  Just do not ever try to get away with shucking the jacket off a cable to get at the wires inside -- wires inside cables are not marked for use outside the cable jacket!

At the ends of the conduit, you'd put a box and transition to a cable wiring method there

With individual wires in conduit, the conduit run needs to be complete between boxes.  So, this simply means you need a suitable box at each end of the run, mounted indoors, that you can make splices in to transition between NM and wires-in-conduit.

Run another conduit for the networking wires

You can't put network or coax cables in the same conduit as power wires -- this is governed by 800.133(A) and 820.133(A), not 300.3(C).
