House built in the early 1900s. Half of the house has a basement, the rest has a type of "Torpargrund." The joists are starting to let through the sawdust and seem to need replacement. We plan to tear up the floor and "start from scratch." Slightly sloping plot. "Kantbalk"/foundation of stone. Space under the joists about 20 cm, to a bed of indeterminate material, filled on the ground. The plot is high-lying, no major drainage issues. We have previously removed "torpargrunder" in older houses and replaced them with a "slab" according to the sketch, which seems to work so far...? Any tips/ideas?

According to the picture, the torpargrund looks very dry and nice. I would keep it but dig it out a little and remove all organic material.
I am doubtful of your construction of modern mullbänk when the cell plastic is placed so high up in the construction. It's basically like a vapor barrier and it would likely get very moist in the layer below, if it faces anything organic like a wooden frame it might not be so good.

Why replace something that has worked excellently for a hundred years?
You have a well-placed house on good land with zero moisture impact in the foundation. Clean away sawdust etc. that has fallen down, lay a new subfloor, and fill with breathable insulation (cellulose or similar).
Why introduce the risk of implementing solutions that do not breathe in a house that is designed to breathe?
Especially when you have such well-functioning foundation stones, and the only problem you have is that a bit of sawdust insulation has started to leak out. From what it looks like in the picture, the leaked sawdust is not even a direct technical problem for the building, but mainly a comfort issue regarding insulation. (at least within a limited time frame)
