From the lounge perspective....
QF F lounge at LAX (
https://onemileatatime.com/qantas-lounge-lax-review/) will put the Fiji (shared w/ other airlines) lounge (
https://onemileatatime.com/los-angel...ge-lax-review/) to shame with one hand tied behind it's back.
If you are into the lounge hopping side of things.... AA FL at T4 is a decent plane spotting location w/ OK buffet and drinks, OW J lounge is also a nice quite spot to relax but not much in terms of outside views, and then a good meal at QF F before you get on board!
