CRO go through the same school house that PJs do, training beyond that is unit specific. And in my experience, you're wrong in that CROs do everything PJs do. They do end up being the guy in charge on the ground vs. actually sticking people, but they're just as qualified as the PJs.
my order would be
CRO
CCT/STO
COMBAT WX/COMBAT COMM (tied)
MX
whatever
my first choices are all tip of the spear types, then you get into MX, which is probably the most leadership intensive careerfield out there.
