Opponent was 4tabling reg.

Preflop I expect him to call my raise with something like 22+, A2s-AQs, AJo-AQo, KTs+,KQo, Q9s+, QJo, J9s+, unsure if people defend JTo pre... but he will definitely defend T9s, 98s, 87s.

Not sure about T8s, 97s, 86s, 75s. Do people defend these hands? And mostly aggressive or passive?

Anyway I cbet this flop with full range and expect him to fold all his Ax with backdoor flushdraw and everything that totally missed.
He will sometimes float stuff like KJdd or KJcc I believe.

Turn I hit the double bellybuster and I can rep a big hand since I raised UTG. I can imagine that I should bet bigger like 1,3x pot or something so I can shove the River more comfortably. The plan with my hand is to bluff on clubs and to valuebet when I hit and checkback when I hit a pair.

River is a club and I can easily rep a nutflush and his range should be somewhat capped. His only nuthand should be AJcc and possible AQcc.
But now the question is if my bluff is +EV since he can easily bluffcatch me when he holds the Ac...

Now that I think about it Turn overbet makes more sense so that the SPR is better on the River.
