Some apps are just better behaved than others - YouTube tends to be on the worse side, so you'll see reloads even on iPads with lots of RAM.
iPads in general are pretty long lasting - I would have continued using my 2020 12.9 if I hadn't suspected (correctly) that the move to OLED would come with a redesign and I'd be forced to buy a new Magic Keyboard as well. So I upgraded to the M2 while it was still available, and I expect I'll get at least four years out of it before I start considering an upgrade.
That's about how long I used my iPad Air, which I only replaced as I was given a 10.5 Pro through work.
