Hello fam!

Looking for some input regarding this hand. Will break down the hand below and give you my thoughts. Will ask my questions in the end.

Flop: I expect him to Cbet all his strong draws, Ax suited, Qx suited, Tx suited, Top pair good kicker on the flop as well as a lot of his value hands as it's a draw heavy board. Maybe KK and QT will check back here some of the times with the intent of raising. Is this fair to say or do we give him more c/calling combos here?

Turn: Block betting 1/4 of the pot here feels like a very weak line to me. I would expect flushes would c/r a lot on this spot or raise larger, same with QT. Kings would C/call but maybe a few Kx with a low kicker might take this line at NL20 from a bad player.
Over his range i believe is composed mostly by drawing hands and fdraws with possibly a pair.

River: After he checks I believe he has A9, AT with the A of hearts a lot, Jx with a heart, some random 89, Tx and Qx with hearts so I go ahead and bet 3/4 to try and get value from Jx. At the point I felt confident he almost never has a value hand that beats my trips.

What do we think is the opponents C/call range by the river?

Are we ever beat on the river with the line villain took?

Should we be doing something different at any point before the river?

My thoughts: Retrospectively I feel this should be a 1/4 to 1/3 bet pot by the river as i feel there are more combos that will call a weak bet than not.
