I had a music teacher who'd wanted to play jazz and started with a saxophone. She stopped very quickly because she had absolute pitch and couldn't come to terms with music not in concert pitch. "I try to play a note but the wrong note comes out and I just became very confused".

My own preference, I think(!), would have been to learn the different fingerings for the instruments for concert pitch, or just choose one instrument and learn only it ... in concert. I did that as a child with recorders (C and F), but maybe I'm being naive about it. AFAIA the mouthing and breath control of the various instruments are sufficiently different and one really has to fully learn each instrument anyway, so I'm unclear if the different pitches really help.
