I generally lead out in these spots, and big like $30. This flop rates to get you action. I'll continue with a turn barrel unless it's an Ace. If the flush comes in OTT, what I do depends on how many players and what reads I have.
C/r flop has merits but is a little too strong. We don't want to blow out Ax and it kinda sucks if we get raised back. On this exact flop, I would like c/r with a hand like A

where we can fold out better Aces and get called by worse FDs.
As played OTR, I'd fold. He likely has the Ace and if he somehow has KQ, we're still beat. He could have a busted draw but then I doubt he would have made that comment about you not having anything.
