Of the places you’ve stayed, SSR is the only one I would personally buy unless you decide you absolutely love someplace AND need home resort priority for your desired room type and planned travel time (e.g., December).
I know you have expressed some, shall we say, lack of love for CCV. Here is a tour
DVC fan recently did of their renovated 1 BR villas that might interest you:

In case you're still reconsidering CCV, I do think CCV points would get you both an ability to secure 1 BRs at WL during high demand times and points that have some of the best long-term value in the eyes of many.
That said, definitely agree about waiting for dues info to come out and for resale inventory to pickup in the next few months. You might also want to give some more thought to the right UY. You've expressed some desire to travel in December and not liking the summer. A September or October UY might be ones to consider. September is one of the lowest traffic times at WDW and also the lowest
point chart, although it is still hot and hurricane season. Just some things to think about. Personally, I would not be one to just go searching for any contract with any UY, even if it were a deal. I'd want to secure the UY I prefer, or at least one I think would work well for my planned travel.
