Short, but nice article on double brick housing in WA. It’ll be interesting to see how the home construction industry here changes in the coming decades.

The rammed earth i’ve seen has been thicker than two bricks, and had no cavity. Maybe the properties are similar, but magnified?
Maybe. I haven’t heard of rammed earth keeping a house hot. I’m guessing that’s the cavity in the middle holding hot air.
It’s mass that holds heat. Rammed earth is great if you don’t let it get too hot (so needs shading), or if it’s insulated (the best way).
For almost all of Australia bar the tropical north, the best construction is insulated mass - ie cladding (lightweight or not), then a cavity, then loads of insulation and a Vapor membrane, then masonry.
And my house currently has one of the four layers you suggest. I might just have to save your comment, i’d definitely missed the vapor layer and a cavity behind the cladding.
Na, nor have I.
