The questions aren’t getting any fewer :-( Today, we looked into different home builders again and still can’t really figure things out. Surely, there are many good builders and also some less good ones. As a layperson, I find it difficult to judge what is good and what is not. Regarding insulation, I wanted to ask: what is actually better? Filling the interior wall mechanically with cellulose or using mineral wool in the traditional way, or does it make no difference?
Thanks very much for your answers....

It is difficult to say in general whether one option is better or worse. For example, gold would be a poor insulation material—expensive and ineffective at insulating (though it probably offers decent soundproofing 😀).
I think you should first clarify some fundamental questions and avoid putting the cart before the horse.
Have you already decided whether you want to build with solid walls, such as a masonry interior wall, or with wood?
Are you ideologically committed to sustainability, or do you not mind either way? Is petroleum and plastic the enemy, or do you have a more neutral attitude toward them?
Do you prefer a “castle” feeling, or is a protective clay roof sufficient for your comfort?
Do you want extravagant architectural shapes, or a typical, simple single-family home?
Do you have money to burn, or is being economical important because of budget constraints?
Does the building need to have a KfW certificate with a star displayed on the wall at the end, or is that not important to you?
Do you want your grandchildren to be able to live in the house as well?
Are you fond of Sweden and want to evoke that Astrid Lindgren atmosphere?
Do you live near a highway or in a quiet valley away from the world?
Are you bothered a lot by heat in the summer?
Are there rules from the zoning plan (building permit / planning permission) you need to follow?
Are you terrified that your facade will look terrible after a short time?
Is there a coal power plant or industrial area nearby?
Are you worried about woodpeckers or your children playing soccer against your exterior walls?

UI, to briefly answer the many questions in order, here are the responses.
Timber frame construction, prefabricated house
No, not necessarily
No petroleum, no plastic
Standard clay roof tiles
Normal, plain single-family house
Not very wealthy, but willing to invest in quality; it should definitely meet KfW 55 standards, no cheap mass-produced house
Grandchildren? If it lasts that long...
Wood house with exposed ceiling beams would be nice
Forest area
Heat in summer; I’m not sure how that behaves in a wooden house
Facade deterioration is inevitable sooner or later
No power plants nearby
Not afraid of woodpeckers or soccer balls
Regarding the question about timber frame construction: How thick is an exterior wall? More like 190mm (7.5 inches) or 240mm (9.5 inches)?
🙂

More like 190mm (7.5 inches) or 240mm (9.5 inches)?In our case, the stud frame alone is 165mm (6.5 inches) thick, but there's quite a bit added on top of that. The exact thickness depends on the supplier, but I would expect around 300mm (12 inches) or more.
Then you have answered your initial question—if you want to avoid petroleum-based products, cellulose insulation is quite suitable for you. It also fits the given conditions.
When in doubt: a thicker insulation layer results in more energy-efficient houses (at least with less heat loss through the building envelope). Since the price per square meter in the forest certainly isn’t the same as in central Munich, the main argument against thick walls no longer applies.
