Questions like this almost always come down to microscopic blocker effects.
The Jh blocks the only J9s possible, while Kd/Kc blocks KK and K9o in villain's range.
There's some value in understanding how your suits interact with the combinatorics of the board, but not a ton to take away from this spot.
When in doubt, look at your equity, then try to work out what value/bluffs you block/unblock in villain's range. If villain's range isn't visible, select multiple nearby bet sizes to get an approximate answer.

Clearly, this isn't a beginner question, and I agree the Poker Theory & GTO forum will be the best place for these kinds of questions going forward. I don't think we can fault Satti for not knowing this though
