"Does the single-reed and straight tube combination determine closed tube
behavior?"

Although I have posted this peculiarity in the past, it is time for a
repost. This is an experiment you can do yourself and it complicates an
already complicated situation.

If you will take a clarinet, remove the mouthpiece, fashion a cork with a
hole in the center, place the cork in the upper end of the barrel, and
insert an oboe reed in the hole, playing it will result in the instrument
overblowing an octave. What this says is that the characteristic of
overblowing a 12th must come not from the straight tube but rather from the
mouthpiece and single reed combination, though I have no idea what causes
the mouthpiece and reed to behave the way it does.

Go figure.
