Take a look at Linkding. Run the latest-plus version to archive pages and get reader mode features. You can use Linkdy as the Android app for it. I’m unsure about the RSS features though.
I think a separate FreshRSS container would be better for that though, and you can use ReadYou as the Android app.
Wait, is that possible? I thought gadgetbridge didn’t work with Garmin! Nedd to check this out. Thanks for the inspiration!
