I'm in the process of getting rid of as much Google-related stuff as I can. Yesterday I already started with moving everything I had stored in Drive (backups and other stuff) to my Nextcloud and the like. Now I want to change my main email, the one I'm going to use for, my accounts here in the fediverse and so on. So I'm looking for alternatives.

At the moment, apart from Gmail, I also have an Outlook (from when it was hotmail), a Proton account (though in view of their CEO's recent statements I may not keep it) and a new one on Disroot.

Which of the aforementioned services works best for a normie not well versed in cybersecurity like me?

Do you know of any alternatives I'm not aware of (I've heard of Tuta, but nothing else)?
