Show Gutenberg editor blocks only to target audience depending on their user attributes such as user role, log in information and user names.

This plugin redirects non authenticated users to a page of your choice or, as per default, to the login page. 
Posts, categories, feeds, tags, taxonomies, author pages and search results are restricted to authenticated (connected) users. 
Only pages are public. So if you have a homepage defined, then this page will be accessible.

Very basic content restriction

Restricts access to all content except pages for non authenticated users.
