Always ! :)

Agreed.

But does the frequency the cavity resonates at have to be present in the chords, I suspect not.

True for the fundamental, but what about the higher partials and singers formant ?
I realised that the trumpet analogy might cause some problems because of the flexibility of the lips. A better case is the clarinet or saxophone. The reed, I think, only snaps open and closed, at a frequency tuned by the players lip pressure and the instrument. However, what comes out the end of the sax has many overtones and complexity which I don't think can be present in the reed. So the resonant cavities are adding tone to the sound initially produced by the simple vibration of the reed.
So as not to lose direction of the discussion, the point is that trying to equate the sound produced with the mode of vibration in the chords, may be mistaken. Saying 'because the sound is rich it can't be falsetto' may be erroneous if the 'richness' comes from shaping of the cavities, even for a simple vibrational mode in the chords.
