This might not fit your workflow, but Thunderbird can be used as an RSS reader. Go to File > New and add a new Feed Account
I was hoping for this to work but it doesn't parse the full content. Weirdly also it didn't import correctly the opml file, the folders where there but they didn't have the rss link.
I just imported an .opml with folders into Tbird 102.13.1 and the items in the folders were there. I don't know about the parse full content part.
Emacs
FreshRss! It’s a selfhostable web app/server with a browser reader.
The full text extraction takes some technical fiddling and reading, but it works like a charm!
Can't go wrong with Fluent Reader. It's beautiful and featureful, has a reader mode as well.
Nextcloud's news reader is pretty good -- but you need to host a Nextcloud instance first :) (Hint: you should, to free yourself from google/icloud or whatever you use)

Desktop and mobile clients are available.
Wallabag might work.
I use newsflash for this, not the best app but still does all I want.
Liferea does the job and worries pretty well.
I tend to use either Newsboat or Elfeed. The first one is command line, the second is Emacs. So they're both text-based. Might not be precisely what you're looking for, but with the right choice of terminal font and easy-on-the-eyes colours, I find it a pleasant reading experience without distraction.
I'm a fan of KDEs Akregator. It does a great job as a feed reader and shows the contwnt of an entry in a simplified reader mode. However some feeds jist dont display the full arricle in their feed entries so you'd have to follow a link there. But even thats sth that makes Akregator awesome: you can specify the command thats used to follow a link and most browsers have the option to open a page in reader mode via the commandline. So from what I gathered thia should pretty much do all you want it to and then some.
Feedbin. Not a Linux app, but a web app. And not FOSS or self hosted. Just a really great app run by great people for a great price. Parses full content and has a pretty nice API.
Akgregator is great but I'm not sure about Reader Mode
Nunti
Self hosted, very simpel, runs in browser (therefore accessable cross-plattform, mobile and desktop) and looks good enough.
It was my initial idea to consume news after reddit died for me. Thankfully, Lemmy files that gap <3
Gnome Feeds
rss2email combined with any mail client
(best to use some dedicated mail account though)
If you're not afraid of the terminal, the combination of newsboat and w3m is the quickest option.
I am using feedpushr which sends articles to my mail.
i use freshrss, and rssbridge to aggregate my feed device independenty (so i can have the same feed on my phone)
Gnome Feeds works well for me.
Anyone else remember Google Reader? Not OP's question, I know, but holy shit was Google Reader good times.
ttrss might be an option if you're into self hosting
From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.
