They're all equally canon as the live action stuff.It seems to have basically become very similar to the Trek policy (just with a few more winks and complications), filmed live-action material is canon, the current animation is canon (winking, a lot less so than the live-action stuff), the (Disney era) literature is (multiple big winks, kind of not really), everything pre-Disney aside from the films is not.
What you're describing is how the old EU did it, with different layers of canon.
