agree the UTG limp could be suspicious (or donkey)

but i'd prefer to flat the iso raise here and not 3bet OOP – b/c we aren't keen to get 70bbs all in pre w TT vs unknowns 4bet range

and it would just suck to get 4bet and have to fold

as played i like the flop check and your turn sizing is fine

i would also prefer flat pre,

check call the flop is my line too and the turn sizing is also fine

If no reads on villains I flat pre and see action from limpers (limp shove means AA-KK almost everytime at these stakes).  Check Raise flop. Follow up turn

As played your sizing if fine, both of you have plenty chips left to put it all in OTR without overbetting.

Flat pre-flop, betting ~2675 into 4725 (from flatting vs. 3 betting).

This then leaves all over pairs to possibly raise and feel committed and bluffs to do their thing.  10,075 on turn (if called) and I would donk lead again this time for 5200.  If called the pot would be 20,475 and villain would have 14,528 left making it probably a given to get stks in on river.  When you can achieve getting stakes all-in on river when your shove gives villain 2.4:1 on his river call (14,528 to win 35,003) than the 3 bet pre can take all that from you when he 4 bets big and then you have to fold.
