Window connecting elements (wood, slate)

That is absolutely no problem. Behind it is simply masonry and ETICS, then on top of that. Facing bricks or whatever you like. Window manufacturers also offer coupling elements.

That is exactly the question here. What does it look like when building in monolithic construction? Is the plaster buildup sufficient to install either counter battens plus rhombus slats or clinker slips?

How many cm of plaster buildup are normally applied?

On average, about two and a half centimeters of plaster are applied, which would barely be enough for the battens. Slips can be glued reasonably flush, at least the joints, otherwise it would probably look odd.

That is then the question: whether, on the facades you want to design like it is fashionable with ETICS buildings, you still switch to ETICS. Your house design is rather atypical for the monolithic faction.

Your house design is rather atypical for the Monolithiker faction.

That's why I'm asking here. So far, I have held back quite a bit with my architect and have given him all the freedom. Once there is a draft, I think we can address the details. It might even be necessary since it is already clear, for example, that the ceiling of the covered terrace needs to be insulated.

I am a fan of being able to do without insulation if the required values can be achieved with an aerated concrete block.

That was not at all the impression I had so far: the "terrace ceiling" is only one detail; I also mean to recall a cantilever of the floor slab intended to act as a kind of profile strip for the facade. As far as I can tell, this does not at all smell like an effort to avoid unnecessary insulation contortions.

I have already abandoned that, precisely for the reasons mentioned. As you have already said, I also agree with you that an effect can be achieved with the right proportions.

In summary, my findings are that with a monolithic construction method, i.e. aerated concrete or Poroton, it is rather more difficult to implement the design details.

Perhaps another point: Are there problems with the monolithic construction method in combination with large window surfaces?
