Thanks for the thoughtful responses.
I didn't really want to post anything else about this because I'm kind of embarrassed about my play in this hand. Here are my answers to the questions about my own thought process during the hand.
Preflop:
This call is a little bit loose but I've been 3-betting a lot this session so I'm not inclined to squeeze even though I think all things being equal I should probably be squeezing here like 30% of the time at least? I also thought that I could lose a big pot to a bigger ace but some of these guys just seem arrogant to me, like poker's their one source of pride, and they probably see me as a basic donk who tends to overplay his hands so I think there's a premium on getting a big hand even though I'm not all that deep.
Flop:
I play mostly 5-5 and after the original raiser (UTG +2, sorry) the 5/12 pot bet from the CO just looks like too much of a steal to fold especially when he knows that this flop isn't going to hit the preflop raiser's range or my range very frequently. I just don't see a lot check-raised flops at 5-5 so I wasn't that concerned about a check-raise. I thought it'd be pretty risky to try that with an overpair that's not aces against two opponents and it could also leave him in a tough spot if he gets 4-bet on the flop with such a wet flop.
Turn:
After he checks the turn absent a soul-read I think I need to bet. My hand is quite strong and it looks a lot like I might also have a draw and just be trying to force him out of the pot. In retrospect I think the sizing might be a little small. Against the check-raise, I think with kind of an unknown image maybe this is where I should have known better, honestly. There are some players that are just going to call you down so light that a bluff check-raise never makes sense. Vegas tourists who play 5-10, in general might be one such demographic. Only one guy at the table had seen me before and I was giving a lot of action that session based just on having pretty strong cards so I may have looked kind of LAG. After all the card removal there's only 2 combos of A4s and A5s, Ah4h and Ah5h, maybe Ah3h for a chop but he might have raised some of those hands as good bluffing candidates preflop. Other than that there's 7 combos of sets assuming he never has AA here which I think is a good assumption. My reason for just calling the check-raise was that I kind of thought that this guy was a barreler, a player who when he bluffs tends to bluff multiple streets, and if he had a draw he wasn't going to give up on it on the river but I think if a third club comes on the river then I can probably find a fold and if I raise he's probably calling with clubs, which are probably higher clubs given the board and he might think that if he pairs those cards they're good and and he might think he might be ahead anyway with his AcXc or KcJc whatever. I'm not saying this was a good reason in retrospect.
RIVER:
I don't think the 2s changed much. I can't think of any hands with a 4 in them that he might have except maybe Ac4c and he might raise/folding that preflop. 3 combos of 64 suited, 6 combos of 44 but I just don't think those are in his range. I think my hand is probably underrepresented. He might have been going for a steal on the flop with like AJ and just hit the ace on turn like I did or it might be clubs and he might figure it's no good after I called the check-raise on the turn. It sucks either way but I think if I fold it's just too exploitable.
SPOILER:
He had 66 for a flopped top set.
