I mainly had bad experiences when trying to mix packages and hand build QGIS on the same system. Since I don’t use packages I have every version of QGIS installed for the last 6 or so releases in a pattern like this

/usr/local/qgis-<version>

I have little launcher scripts and .desktop files so that you can simply launch whichever version you want from gnome (or whatever DE you prefer). This all works seamlessly without any issue. I also have docker launchers set up in a similar way. Although I am a huge fan of docker, I actually think building multiple binaries into different prefixes gives you a better experience and would be my recommended approach if a user is able to compile themselves. I’ll make a little repo with my start scripts and .desktop files if that is useful to anyone (you just need to ensure you use the same INSTALL_PREFIX convention I do.

Regards
