Building Survey

So I am starting to plan out my next structures now that I've gotten nearly all my functional structures down with early game stuff (at tin-bronze) and was wondering what people tend to build with mid to late game?

For reference most of my structures consist of wood and cobble with the oldest buildings being rammed earth and mud bricks but I want to step above them both. I would love to start using blue clay shingles for roofs but idk what to do walls, floors, and so on out of and I don't want to begin building it only to find sourcing a material is a pain in the ass. So suggestions? Comments? Calling me a nerd? All good.
