On Facebook, if you go to 'Menu' > 'Feeds' > 'Friends' you will see a feed of only your contacts' activity and none of the suggested posts & random pages on the normal Feed
Holy crap, I knew it was there but didn't think it let you go straight in via a link. Turns out https://www.facebook.com/?filter=friends&sk=h_chr is more or less what I've been looking for for a few years...
In fact https://www.facebook.com/?filter=all&sk=h_chr might just be perfect - it's got my friends, groups and the handful of things I am interested in, in chronological order, and nothing else. Amazing.
