The general policy regarding Legends/Canon composite is that you use their best showings from both as the standard. Personally I think we should simply operate under he assumption that Canon overrides Legends where there is a contradiction but that's just me.
Regardless you are getting muddled by mixing narrative events with feats, Vader may have never collapsed a cathedral in Canon, but that doesn't mean it's an accurate representation of what he can do, so they are easy to blend it that way.

But trying to make sense of it just...doesn't really work as I see it for some material.
If you compare TCW characters to Legends CW material, you'll see difference in overall power, dueling, strength, durability and so on.
So...how do you cram those things together and make sense of it??
