Ice is the best Menu Bar management tool I use on my Mac, and it's completely free and open-source

If you use a lot of applications that insert themselves into your Menu Bar on your Mac, then you've probably run into the problem of having them clutter it up and even force icons off of the screen. There are a lot of applications I've installed that have a Menu Bar item that I never interact with, like ChatGPT, Alfred, and LM Studio. Plus, when using tools like Stats, you'll realize just how little space there actually is. That's why I use Ice to manage my Menu Bar, and it's been an absolute game-changer.
