I think a lot of these guides could use more in-depth companion guides to go along with it. Changing your email provider for one is not a simple thing and there are concerns like loss of functionality (Gmail is a good product run by a shit company) and also how to make the process less overwhelming. Some services will give you the option to migrate all your emails from Gmail but maybe you want to start fresh, etc. Then there’s going to all of your providers and updating your contact email. Again, not as simple as signing up for another service.
