Which configuration with JFET or BJT would yield the highest performance
and least jitter?

AFAIK a well-designed Butler oscillator will have the lowest jitter, but
I doubt that you could do the "well designed" part without a lot of
bench work.

Any of the rest (considering a "Clapp" oscillator to mean a crystal
oscillator with rubbering) are good enough for communications work.

FWIW, ADI recommends a Butler oscillator for use with their DDS chips,
for minimum jitter.
