My goal is genially not to have anything running in the menubar that isn't out of the box from the OS. I had a similar desire with the system tray on Windows (though it was more difficult on Windows due to some hardware requiring it).
Work is the only place I have an issue, because they install a bunch of security agents that all want a spot in the menubar, even though they never need me to interact with them or know what they're doing. Those agents sitting up in the menubar tend to be the reason my system has slow downs or issues. Though the slowdowns have gone away since moving to M1. On Intel my fan used to run all the time. Now I'm just left with the weird issues they cause.
