Pre and flop ok, 

OTT your range is incredibly strong and i expect a lot of c/f. 

I'd go with a small bet with my entire range since I'd certainly want to bluff my non-Axxx hands here.

no need to go more than 30$ ott, imo. i more interested what the plan is vs reg on the river, if called.we block JJ, but not sure if he's folding A2** or worth 2*** for river shove (depends on your 3b stat and his wtsd)

OTT sizing depends whether we are going to triple barrel or not

pre std as you said, flop def. cbet small i would go 18$ but 15 is ok too i guess. I dont really know what you mean by no worse hand would bluff me in this pot. I think that players like the aggro button could bluff here with a hand worse than yours. He knows your range is very AAxx or highcard heavy and you will almost never have a 2 in this spot. So he could easily bluff raise the flop with Jxxx hands or any kind of pair (to have some backup equity) to get you off your overpair. It would be very hard for you to call 3 barrels here with AAxx hands

OTT I would def bet small against with my air here, the question with your actual hand is if you belive that you can get him of a 2 or not OTT or OTR because you certainly wont get value by hands worse than yours and i dont think ppl will float here often and will bet the A OTT which hits your range very hard.

About him holding a 2 :

1/He's calling a raise pre and, given his reasonable stats, shouldn't have many deuces in his range.

2/Consequently, he shouldn't be bluff raising this flop often at all as he doesn't rep much and should be keeping a fair amount of JJXX in his c/c range.

3/If he has a deuce he certainly won't, and shouldn't fold against a turn bet unless you are an incredibly tight 3bettor.

Turn is pretty much a way ahead/way behind spot. Either villain has 2 and we are drawing to 4 outs or he has J*,QQ,KK and has 6 outs at best (if he has a wrap a few more I guess).

By betting we can end the hand (which isn't too bad with $70 in there) and can define villains range. If he does call OTT (even vs a small bet) he has AJ, JJ, 2* almost always which makes river an easy x/f. If I bet, I'd go for $28 or sth. Sets up a nice rivershove and again, vs villains range we don't need much protection at all.

Checking: As I said, I feel like we are way ahead/way behind here, so from my nlhe days I immediatly think about not putting much money in. 
Checking vs worse hands can either lead us to showdown vs worse and would therefore be close to same EV than betting vs those hands except we do give freecards to his QQ,KK (which oftentimes will have a gutter).
Vs better hands: If we think the probabilty of him turning KK,QQ,J* into a bluff vs our turn-check, is low, x/folding OTT makes sense since we don't have to be worried about folding vs worse much at all.

As a conlusion, I would decide to bet $25-$30 here. With our range we don't have to proctect vs too much. Either we have a boat, top2, TP+gutter or we have air which is already behind.
In villains shoes: He will either sit on J*,QQ,KK and face that bet + the possibilty of frequent rivershoes + no to very few outs which will result in many folds or he will have 2*,JJ,AJ and very likely not fold anyways. -> We save ourself monies by betting smaller.
Fwiw, if called OTT I'd not shove river with our hand and most definetly not if I had a bluff since SPR is gonna be very low and we won't have much FE if we have an air-hand.
