What about planes with multiple fixed guns that had different amounts of
ammunition/fire time -- did the pilot have a selector to determine which
guns would fire or did everything fire when the trigger was pulled and some
guns would run out first?

Generally speaking, where the planes were equipped with homogenous
armament (e.g. eight .303s or six .50s) they all fired together,
without the option. Where a plane had mixed armament (e.g. cannon and
MGs) it was possible to fire them separately or together.
