It would be cool if one day (if not already today?) you could use AV1 as a drop-in replacement for h264 for recording with OBS, smoothly editing without proxy clips and rendering out highly disk size efficient videos that look good.
DaVinci Resolve's free version on Linux does not support h264 but apparently does support AV1. Kdenlive supports both. AV1 sounds like it would be a great solution for Linux if the above is possible.

I started looking into converting stuff to AV1 but only confirmed that my gpu doesn't support AV1 but does support hevc so I stopped there...

Every form of lossy compression deleted data. Yes AV1 is more efficient but only when working off of high quality originals.
H265 already deleted a ton of data. It can never recover the quality loss. Compressing even further can only worsen the image.

For what it's worth, AB-AV1 [1] is a pretty awesome tool written in rust which compares random samples from a file at different parameters based on their VMAF score [2] (algorithm from Netflix for human-perceived visual likeness), choosing optimal parameters to save as much space as possible with the loss you're willing to stomach, on a file-by-file basis.
Small plug: I made a nice little python GUI wrapper for ab-av1 [3].
