Definitely play this hand preflop vs 2.4x. BB vs SB when SB is FRI is where you should call the most.
You'll see good players defending 60, 70%, even 80% of the hands on the BB.
I lean towards calling, but 3betting with weak suited hands will be profitable in position. Mix it up, but call more when SPR is bigger.
Remember you are capped OTF. You don't have any overpair, JJ in your range. Top of it is Jx, 55 or 33. Due to it I believe calling the cbet is better, unless villain is cbetting too much and opening too short on the SB, which doesn't seem to be the case for a 27/27.
Please explain why you like the flop raise. I would rather raise to protect a Jx hand than a weak pair.
OTT you hit your flush and you don't have the nutflush draw. For that you need the K♣:.
I would bet bigger, anything from 80% to 150% should be ok.
Villain's line looks very strong to me when he bet/calls the flop, check/call the turn and leads the river.
Nevertheless, you have a clear call with a flush.
Notice villain didn't check/shove the river, neither donkshove. He simply bets 29bb on a 38bb pot, with 83bb behind.
