What's the next step in repair? Pulling the wire to the niche and
replacing --- or is pulling the lamp housing up the surface for
inspection next?

Check the fixture. Not a big job to remove and disassemble.

Regarding the wiring, wet niche lights are typically wired with just UF
cable directly buried in the backfill. The via into the niche is just a
1/2 ID tube that is filled with caulk. If there's a problem inside the
niche or the via, then you may fix it. If the problem is some buried wire,
then oh-oh.
