To answer your original questions:
There is no glass ceiling in AFSOC for CSO types.
Leaving AFSOC is possible, but generally difficult unless your circumstances allow (ok manning in unit/crew position, on-board commander, etc.)
Good on your for choosing mission over everything else, but don't sell your stick-monkey potential short. You aren't born with piloting skills, they are taught.
If you really want to be a CSO, go for it...you can always change your mind later and apply for pilot training up until you are 30. It is not uncommon. You have a long road ahead of you and you could end up in a variety of airframes as a pilot or a CSO that you may not like. Work hard enough and don't be a douche and you can generally end up wherever you want.
Also a bit of advice: if you do end up going CSO keep it to yourself that you passed up a pilot slot. No one will believe you, and it can only hurt you.
Best of luck.
