What actions are triggered when creating / registering new users?

I often need to “do something” when new users are created on my Wordpress site. The only action hook I know I can count on is this user_register.

The problem is that I think that it works relatively early in the process of creating a user, so often there is no user information that is not available, or other plugins make changes after that caused by my functions.

I researched, but no luck, what resources explain how WordPress creates users and which interceptors fire when?
