Also kind of a bad question, because too much will depend on the base, the mission, and the leadership team and coworkers you have there.
As a general rule, aircrew, medical, and personnelist jobs are chill and ops and maintenence jobs are not. But even that isn't completely accurate: NDI jobs are known to have a lot of cute broads and be chill but NDI falls under MX...
A more useful question will be what jobs you're qualified for after medical and ASVAB are taken into account.
All this planning you're doing right now is useless: every job you want might either be unavailable or you might not qualify for.
