Removing a load-bearing wall, experiences?

Yes, fish and for her rather onions literally upset her... She still finds garlic tasty.

And didn't you ever leave the doors open as a trial in the old apartment? (I would do that when planning if my sweetheart had a problem with olfactory imagination)

The strange and completely irrational thing is: In the old apartment, we also already had an open kitchen. Honestly, I have no idea whether it is purely psychology, the central ventilation, or the chimney effect you mentioned that makes it unbearable in the house now, which was still barely tolerable in the apartment. Or I just cook more strongly smelling dishes than before - no idea.

No, people and their needs or animosities simply change over the years. That's just how it is. Rituals or habits also change over the years within a partnership or family. If you used to have visitors every weekend cooking gourmet food with just one child, you do it less now and instead cook home-cooked meals for the family. You might become more sensitive. One person is like this, another like that. That's why I always think it's good to plan open kitchens in such a way that you include an imaginary line for a wall. But that shouldn't prevent anyone from enjoying or enabling an open kitchen. You just shouldn’t underestimate a wall or a partial wall, especially when it concerns the entrance or the staircase. But the question still remains as to how it is now at the moment.

Have you ever checked which supply lines (electricity, water, heating, etc.) run through the walls to be demolished? The effort to possibly relocate them must not be underestimated. Especially if there are electrical distributors or heating circuit distributors located there.

Thanks!
As you have drawn it, that is the current situation. Or something similar. The builders had already relocated the kitchen door towards the vestibule back then. I believe the load-bearing parts of the wall structure are located here as I have indicated. (Picture 1)

In Picture 2, there would be a kind of compromise where the "L" could be left standing, of course then in combination with steel beams that would additionally support it.

Even with Picture 2, you will still have to leave a bit of structure everywhere so that the beams have something to rest on.
Although the mentioned point about installations in the wall really must also be considered.
