Hit my weakish flush and facing aggression.

Like 2nd hand at the table. After this hand villain was tight only other big hand was villain flops two pair he just bet all streets after flatting with AQ pre.

Ok so I am like paranoid that he can have like AsQs,AsJs,AsTs,QsJs,JsTs but he can have K9,98,33,88,99,K8(KQ/AK wit a spade) but I think that a set would c/r or donk since the board is so wet. Then on the turn if villain did hit the nutz wouldn't he c/c to keep me in the hand or c/r in order to play for stacks. The only flush I can see that he might have that I beat is 6s7s. I am really wondering if someone would play 2pair/set like this when draws hit.
River do I call? shove? or fold?

Just raise the turn, you're miles ahead of his range for betting and for stacking off. This is sometimes a flush, but it's way more likely 2 pair, a set or a pair + fd that isn't wanting to fold at any stage, just get it in.

A common trait of 25NL fish is to bet a strong but not nut hand (set 2 pair etc) hard on a scary turn that denutifys their hand. I'd weight his range towards these sort of hands.

As played I'm still shoving river, you're hand is underrepped so he can easily bet 2 pair and sets for value and stack off. There are possibly also a couple of worse flushes in his range.
