This plugin is as simple as you expected! 
And it support latest WordPress Gutenberg editor now!
Mark the content you want to hide as restricted with just a checkbox – and it’s done!
In case anonymous user will try to get access to restricted page or post – it will be redirected to WordPress Login page first. 
Or you can specify the exact URL (internal or external) to redirect anonymous users to.
After successful authorization, user is redirected back to the requested page.
Also, it hides restricted posts from Archive and Categories pages, RSS feed and from Latest Comments/Posts widgets!

Anonymous Restricted Content

This is simple enough to use and accomplishes the task. You can protect attachments, which was key for me. Support was slow.

Simple but yet effective plugin to hide selected posts and pages from anonymous users.
