I think it's fine to use vp9, if your browser doesn't support it you're on some legacy ass shit
https://caniuse.com/webm
chrome has supported vp9 since version 25 in 2013. firefox since 2014. safari since version 14.1 in 2021
I was working on a not-so-secret project for a site to give you the ffmpeg command to generate webms. I gave up on it a while ago but I might finish it off this weekend
