I used to memorize all my passwords but now I just use my browser's 'remember password' feature. In both Firefox & Chrome it syncs between devices, and is usable on both the desktop and mobile applications. There's no extra setup required, which was the big selling point (or I would still be memorizing them) - one day I reset the browser. FF e2e encrypts it too.

The only drawback is if you need to login on a foreign device - but that's a pretty rare circumstance, and if I can't remember the password I just reset it. I generate passwords with a pattern but I am saved the hassle of typing them in, and having to remember the exceptions that differ from the usual pattern.

Firefox even offers to generate a random secure password when you are creating a new account! It's a built-in solution which provides most of the benefits of a full password manager with 0 setup or switching cost.
