Please help me learn what I need to know about buying a 2023 GX 460!

I made a bad choice a couple years back and bought a fancy luxury SUV that’s been a pain in the ass and its warranty is quickly running out, making me want to trade it in for a better vehicle. I wanted to find the most reliable 3rd row, 4 wheel drive, off road capable, tow capable vehicle and in my research I’ve come across the GX460 and it checks all those boxes. The reliability reviews and ratings are unbeatable. There’s a couple things I need guidance on:

Luxury vs premium - I don’t care about wheel size or the 17 speaker stereo. I do care about off-road capability and the 360 camera. Do I need the luxury model for this?

Suspension - I’ve read a few people didn’t want the air bag suspension for reliability issues. Is this a thing? I don’t know much about suspension tbh.

What else do I need to know? I’m looking to buy a sub-20k mile 2023 for 55k or less but as much as 60k.
