The most recently refurbished CL rooms are:
AKL (some room renovations are done, I haven’t kept up if they are completely done yet, hopefully someone will know)
YC (1’ish+ year ago)
GDT - brand new tower
After that it’s a pretty steep drop off in terms of when the rooms last had a major refurbishment. Not that any of the rest are bad rooms, they just haven’t been refurbed recently in terms of Disney’s latest resort room trends (eg, hard flooring, more clean/modern styles, etc). Renovations are rumored to be in the works for places like Poly, CR, and WL in the coming year(s).
