2nl 6max - Ah5h vs aggro opponent in limped pot

Today was my first session playing poker in 3 months or so, and this is a hand I wasn't sure about.

I'm 27/21 this session, although 32/18 on villain's table.

Villain was aggro, 37/31/5.5(agg) with a 25% 3bet over 32 hands. I didn't realise until I did a session review that I've played with villain before, and over the 144 hands before July when we played last they were 19/10/1.5 with a 6.3% 3bet.

Villain 3bet me 3 times during the session, first time I raised AA over a limp, I flat and then c/r villain's 2/3 cbet on 6h 2c 9d and they folded. I then opened AdQd and flatted his 3bet ip behind a fish call, and folded to their cbet+call on 9d 4s 8h. The third time I iso'd a fish with KJo, flatted their cbet, turn checked through and I led river 2/3 pot only to get a fold on 4c Kd Kh Jd Jh. I note these purely for the background with the villain (I appear to have the upper hand) and not necessarily for any direct relevance to a limped pot.

There was also another hand where villain 3bet Ts7s vs a fish UTG open and raised donkbet/called shove on Tc 9c 8d for 100bb.

I'm 4-tabling and taking notes but haven't seen villain do anything in a limped pot.

My opinion of villain is that they are likely harming their own winrate by playing too loose and too aggro, particularly at these stakes. I also think their standard 4x open across all positions is a leak with their style.

Based on villain's 3betting I flat Ah5h in the sb so I can play a pot with the open limping fish (73/36/inf over 11 hands this session, 42/20/2.7 over 82 total). I think the flop and turn are much more interesting than the river. Should I give up on the flop or turn and wait for a better spot or follow my read on their image?

I should definitely have potted the flop. I think the flop is interesting because they raised 5x before the fish could act. I was a little slower to call turn than flop.
