Doesn't code also require a bathroom outlet to be on a GFCI? May be
grandfathered but any change of wiring would require it be done, or am
I mistaken on that?

Probably required, but even if not, one would be stupid not to spend the
extra 25 cents (metaphorically speaking) for a GFCI outlet and extra safety.

The wiring sounds perfectly normal to me. If the house is fairly new, the
code allowed for the lights and fan to be on any general lighting circuit
and the required 20 amp GFCI protected outlet, to be on the same 20 amp
circuit as the outlets in the other bathrooms
