Yes, the foundation slab could have been set back a little, but there will still be perimeter insulation added.
With the 20 cm (8 inches) floor buildup and the corresponding insulation, I consider the issue of thermal bridging to be minor.

The standard procedure is to lay the first course one measure narrower and then install insulation over both the first course and the ground slab.

So the plinth will then protrude? That seems like a strange execution.

The ground should be filled up all around up to the top edge of the base plate (OK BP). Then it will no longer be visible.

I just measured the existing walls, and the opening for the living room door is misplaced by over one meter (3.3 feet)… hmm

I can see some seriously poor workmanship there, and right up close to the reveal too. Did you pay such little attention to the standard dimensions during planning?
