Since villain is only slightly loose and decently aggressive postflop, I put him on AQs or AJs. Villain probably wouldn't call KJ preflop.

I really think he has AJ here, and I'm debating check/calling and bet/calling the turn.

If you bet and he has AQ, you'll probably get raised again. If he has AJ, you'll definitely get raised. The plus side to betting and having him raise is that you might possibly be ahead and his turn raise is presenting CO with a coldcalling opportunity (minor plus).

Ok, I've decided. I bet, call a raise, and check call the river.
