Full house over full house over full house over flush. My most amazing live hand so far

This recently happened at 1/2 nl in Las Vegas. I had won some decent hands prior to this so had about $600 in front of me.

I'm in SB with Jh 10h. A few people limp and BTN raises to $10. I call, LJ calls and HJ calls.

Flop is Js, Jd, 10s

I check, LJ bets $15, Hj calls, BTN calls, and I call.

Turn is 7c

I check, LJ almost bets but decides to check, and HJ bets $25. BTN calls, I call, LJ calls. All snap calls.

River is 9s

Now that every draw got there, I lead out for $100, confident that I'm gonna get at least one call if not a raise. LJ now goes all-in for about $250. HJ thinks about it and reshoves for like $320. BTN looks annoyed but still quickly decides to call HJ's all-in. At this point I honestly start to assume that I'm losing to a straight flush, but I'm still not folding. I know I have the BTN beat in any case so I shove for the rest of her stack which is like $400 total. She calls.

LJ has Jc 9d. HJ has a King high spade flush, and BTN has pocket 77s. I win with the nut full house. I don't know if I played the hand the way I'm supposed to theoretically, but if I hadn't slowplayed, none of those players would have made their hand, and I actually think LJ would probably have folded trips before his 9 hit based on his style and my image on this session. Either way this is the craziest hand I've been involved in for my 1 year of playing poker.
