https://bazqux.com/ has long (I think indefinite?) history, text highlighting, a starring system and built-in integration with Pocket/Pinboard/Evernote/whatever.

Keep in mind your history issue is often the fault of the feed, not the reader. If you subscribe to a new blog that only has a year's worth of posts in its feed, then that's what you get. The reader can't proactively follow every blog in the world just in case someone subscribes in 3 years and wants to see the full history.
