I personally think the current ones are fine as they are, though I do like your suggestion “Recommendation” instead of “RT/WT”. Maybe shorten it to “Rec” though, so it doesn’t take up so much space. “DISC” covers most use cases pretty well. By specifying it to “Episode”/“Chapter”, you exclude things like films, one-shots and specials. I suppose you could fine-grain it more, but I don’t really see the point tbh, unless we know it’s confusing people.
