I only listed things that I actually do with the headset.
I do all of my daily programming with it on, there are a bunch of applications to watch movies with IMAX-size screens with it on in multiplayer-synced virtual theaters, there are a surprising amount of full-motion sports, plenty of applications built around socialization including a bunch of games, and it's incredibly easy to develop applications for: It's just an Android device as far as software goes, and as of last year it uses the industry-standard OpenXR, so you don't really need to know much specific to the headset at all.
The only thing you can't do completely standalone that's mentioned in that comment is use that particular Linux-in-RISC-V-emulator-in-pixel-shader-in-VRChat, but that's sort of an edge case, as you can probably imagine. For that sort of thing, the Quest 2 works really well for PCVR, as long as you're not using a very specific configuration of Linux (Linux/Nvidia), or a Mac.
