Answer 2

Hello, before asking a question here, I read on one of the forums that Google's Search Console recommends adding 4 versions of the site, that is: with WWW and without WWW, with HTTP and HTTPS if it exists, and indicate the preferred domain in robot.txt , why?

To set the main site mirror. Formally speaking, according to the search engine, this is 4 takes.
It doesn't matter how you registered it. Prefixes are "service protocols", without going into details.
Then, to let Google know that you own all these duplicates and choose the preferred one from them (added). Gluing.
If you have all the links configured, redirects work, stupidly wait for reindexing
Not
Now Yasha webmaster works in the same way, you can add several versions of the site, you can also choose your preferred mirror
