There’s lots more I could advise doing, but if you’re only using Facebook for reading content you want to get out of Facebook, then lock the whole thing down as best as you can (privacywise) and then use https://facebook-atom.appspot.com/ to suck the data you want out as a feed and pipe it into a feed reader.
You can unsubscribe or unfollow folks to limit your feeds to the bare minimum. The atom feed the appspot tool gives you will be everything and it will be reverse chronological. Good feed readers like Feed.ly and Inoreader will allow you to filter out posts you don’t want to see using a variety of keyword filters.
If you need specific help in setting it up or the instructions are unclear, let me know; I’m happy to help.
If you want to set up and run your own custom private system/server for close family, I can make some suggestions for doing that too.
