Hmm, looks less like AK when the flush comes in and he jams. but TBH I don't think we have to 3bet vs a MP raise unless the guy seems pretty loose. I flat pretty often here, and I think it's actually pretty standard for lots of people.

But yeah, I dunno if people always get AK in PF vs your 3bet from SB actually. This can also be a hand like JsTs that has a good combo draw on the flop so yeah easy fold.

I think you played it fine. Folding flop here is something you can consider but approach very carefully because if you're folding AQ to a minraise and you probably never have A9 or A7 99 77 then you really have to consider and AQ is probably nearly the same as AK in this spot so you'll be folding a toooon. At micros that's not the biggest deal but it's still something you should avoid.

Turn definitely a fold since the main draw gets there and he overbets, I'd expect him to be pretty strong on average.
