There really isn't anything for you yet, just a lot of bad solutions that don't work very well. You might want to wait for Apple's rumored VR system coming out soon, but that assumes that (a) its actually a reliable rumor and (b) you don't hate Apple as much as Facebook.
An RTX 3070 and a Valve Index.
If you've got a capable Windows machine, maybe check out Virtual Desktop
That’s not a VR headset, right? What am I missing?
It's software that lets you stream PCVR to your headset. You're right that it's not a headset or hardware, but getting to play Half Life: Alyx completely wireless made it absolutely worth the $20 I paid for it. YMMV, but if you've got a Quest, a decent router and beefy PC hardware, I consider it a no-brainer. Plus, the PC versions of a lot of these games are just better. VRChat doesn't have as many arbitrary restrictions, Beat Saber lets you load in arbitrary maps/songs to play with, and your game purchases aren't locked in to Facebook if you decide to switch to a better headset (ie. Valve Index) later down the line.
