I would just checkraise the flop. You will get maximum value out of a T or J that way. Plus, while you might win 1 SB less versus checkraising the turn versus an ace, you make up for that when he raises you on the turn with 2-pair or an overly aggressive Ace. Villian will believe he is ahead of many hands that you are checkraising here and will likely play back at you on the turn with these hands. A flop CR is the best way to hide your monster hand, IMO

I don't like the donkbet here because there are too many reasons for villian to just call your donkbet. I think you should have rethought the turn and just checkraised. It looks like it worked out for you.
