Exterior wall for KFW 40 (+) with or without ETICS?

Monolithic means nothing other than coherent, so every completed wall is monolithic or a composite. The only question is which insulation material and where it is located. Everything else is marketing. Today, thermal bridges are decisive anyway. Often the equivalence proof is missing or not given at all. The question is often whether the calculation is still done according to the old DIN or the new DIN. Ecological and economic considerations are the responsibility of the builder regardless.

Weren't you of a different opinion here? ;) Sure... that was 2018. May I ask why you are now a supporter of the filled bricks? Did you have negative experiences with the unfilled ones?

That is called experience value. I myself have a 36.5cm T8 unfilled and we have no problems with noise from outside. We also don't feel cold at 20.5 degrees in the bathroom. Others feel like they're in "The Day after Tomorrow" at that temperature. In other words, everyone experiences it differently. It's just like tastes. But I don't think much of ETICS. I had it in the last apartment. It's not my building material.

And here too, I would appreciate an explanation. What problems or bad experiences were there?

What is so bad about the Styrofoam? You can still thermally recycle the ETICS after it has protected the climate through its insulation effect for 50 years. That’s a pretty cool eco-balance. It’s the YTONG houses with gas condensing boilers that are the worse climate offenders and worth a local FFF demonstration.

Styrofoam is trash that in the end can only be burned because it’s no longer useful for anything else. Whether it actually lasts 50 years is another question. Monolithic masonry lasts until demolition. And the building envelope is completely independent of the heating technology ;)

I believe that nowadays—besides the necessary energy saving regulations/KFW requirements—there is often an exaggerated concern about whether the wall construction is better this way or that. I lived for 30 years in a completely normal house with Poroton brick and neither froze in the bathroom nor had headaches from noise; almost every house in the neighborhood was built that way back then and they are all still standing. Such things usually depend on other and especially very individual conditions like personal feelings, the location of the house/rooms, behavior/upbringing of the children/husbands....o_Oo_O etc., that I fully understand. I also believe that there is often more noise INSIDE the house nowadays than is brought in from outside; only the INSIDE noise no longer stands out as much because it is constantly there and perceived as “normal.” Our house was supposed to be built with Liaplan, but since now another shell constructor is doing it and/or the structural engineer, for whatever reason, calculated everything with brick, it will just be built with that. I often like to think about this, but not right now. I would do that if I really had special requirements like a busy street or other noise etc.

Maybe a little more nuanced.

No, I'm not writing expertise here. Those who want opinions have gotten mine.
I'm done with ETICS! Plastic, soft, environmentally unfriendly - that's enough for ME not to build with it anymore. If anyone wants absolution here, not from me.

How many nails have you already hammered into your facade...?

That's the point: total inflexibility for creative people!

With ETICS you simply have a top insulated exterior with state of the art U-values.

Yes, then... top, but no quality. It reduces the quality of the house!
