I'm not quite sure what you mean, aren't list of things to read very personal and dependent on the taste and interests of the person?

My website has full feed: https://jeena.net/all.atom and so have blogs like Kottke http://feeds.kottke.org/main Marco Arment https://marco.org/rss Scott Hanslemann http://feeds.hanselman.com/ScottHanselman and most of the personal blogs you can find out there.

But as I said, I most probably didn't quite get the question.

But otherwise there are plugins like https://tt-rss.org/oldforum/viewtopic.php?f=22&t=1539 to replace the short content in a RSS feed with the full content from the Website.
