MenuMeters works fine on my Mojave, but from reading release notes it would appear to run on BigSur as well. MenuMeters for OS X El Capitan 10.11 and later https://member.ipmu.jp/yuji.tachikawa/MenuMetersElCapitan/ and https://github.com/yujitach/MenuMeters

Wow, didn't know there was a new version — thanks! I recently booted up my 2008 iMac to get some old files, and I was reminded how much I liked MenuMeters.

Confirmation here: it works fine on Big Sur too.

Pluto requires macOS 11 (Big Sur). It doesn't work on 10.15 (Catalina).

It works, but honestly it needs a visual update because it looks very err... hacker-ish?
