I'm a beginner trying to get a solid thought process and going through hands on the button first.

First hand I chose to review looks maybe interesting, but unfortunately never played a hand with this villain before so no info on him.  Not sure what I can say about the player pool at this stage, I have trouble making observations about the player pool as a whole.  One thing is, donking in single raised pots heads-up seems to be rare.

On the flop the SPR is around 8.5 - generally I should be careful not to overplay non-nut or near nut hands, and look to win money by putting lots of money in when I'm dominating opponents.  So this doesn't fit the latter.

My thoughts on the flop were, if he were at the top of the range he would very likely check-raise rather than donk.  Maybe this donking line makes more sense for dry AAxx but I assumed that was very unlikely.  Wasn't sure of my equity against anything with this weird combo of bottom set and 2nd flush draw.  I chose to get it in if he re-raised.

Some equities on the flop:

about 34% vs. AA**, 40% vs. TT**

59% vs Kc5cQJ

74% vs AT**

I don't plan my hands looking forward from the flop at this stage, can't, I react to the turn card.  So what could I plan, when he donks?  I don't know what to assume.  And then when he calls my raise?  upper-middle of his range?
