Not really sure what I'm doing here. Flop raise should be bigger but then even so what's the plan on the turn? As played river is a call? Or should I be shoving into UTG?

I think raise sizing is OK on flop, I would be betting the turn though and probably not folding.

Lead flop when first to act 3 way on this board. A cbet isn't particularly likely, but a lead will get called nearly 100%.

Bet call turn, push river if called.

I'd go bigger turn and jam for just under pot on the turn for value - we get looked up way more at this stake than just flushes when we take this line (plus we have boat outs).

Three-way on the turn I really don't hate a check here. It's fairly likely someone has a flush, and even if they don't we would be somewhat over-repping by betting again I think.

River I would b/f after it checks through on turn, unless you think someone will turn a hand into a bluff pretty often.
