Villain's pre-flop folding range should indeed be about 60%. (Snowie says 61%, with quite a few light 5-bets, but you won't see those at 5NL). His calling range is going to look a lot like 99+/AK. AQs might occasionally be in there, but KQs probably shouldn't be.
I wouldn't worry too much about trying to use MDF-type frequencies pre-flop. It's true that BTN will "defend" more often than MP does, but that's because MP isn't closing the action. He'd only stick around if he has a hand that does well against the 3-bettor AND the cold 4-bettor. The BTN only needs to break even against YOU. Villain's continuance range is a function of how much equity he's likely to have against what you're repping. i.e. with 99+/AK, he's looking to flop a set, top pair top kicker, or an overpair, and then to play for stacks against a similarly strong range.
That's one of the worse flops possible for you given the ranges (you have a lot of AA/KK/QQ/AK, villain has a lot of QQ/JJ/TT/99), but even if it wasn't you should often be checking the flop in a 4-bet pot when the SPR is so low (I think it's about 2 in this spot). It's not as if you have to protect your equity or try and get value from draws over multiple streets. No one really
has any draws (apart from the AK gutter). You're both pretty much committed to playing for stacks, because there's so much dead money in the pot. Typically, you'd check and villain would either check back or bet small even with hands as strong as QQ/JJ/99, because he wants you to put money in with AK as well as KK/AA. Indeed, if you check and villain just bets quarter pot, you're probably "supposed to" just check-jam your entire range.
Since you led out for half pot, I think that gives villain a chance to fold AK (and definitely any weirdly played underpairs like 88/77), which means your range is is much worse shape when you see a turn, because villain has no total air. Since the Q on the turn makes AA/KK even weaker, you're probably only supposed to barrel with quads and any AKs combos you're using as fairly ineffectual bluffs. Checking AA/KK on the turn seems kind of mandatory to me, and while you're probably hoping villain checks back (as you're in dire shape vs his value-jams with sets), I think when he shoves you have to sigh call, because he sometimes plays TT or KK like this, and might be randomly (over-)playing AQs/KQs or even AJs as well.
Despite this being an awful board for aces, you don't ever bet the flop with the intention of folding at a later stage. When you play a 4-bet pot and you flop an overpair, you're taking it to the felt. Fold your AK if you like, but don't fold aces.
P.S. I don't know if it's standard/common, but I go bigger pre-flop. I mentioned this before, but I just pot it with my 4-bets. I'd make it 30.5bb pre. (My 4-betting range contains quite a few bluffs, so I want to maximise fold equity and prevent villain from profitably flatting with TT/99 etc). Post-flop is even easier when you've got a ton of money in pre. You just never fold.
