Glad to have helped! And a late happy new year as well 😂 A couple of comments on this page didn't appear in my notifs for some reason so bummed out I replied late to some.
As for the sheets that aren't available in the individual assets folder - there are some that I didnt include like you said which are the floors and walls, my main reasoning for that is because these kinds of assets are mostly applied via tilemaps as it would be more tedious to line up individual wallpaper tiles by hand. Though if there is a demand for it I'll definitely look into exporting them individually!
