How to handle walls in lightweight concrete?
Our house was built in 1959 with aerated concrete. We are renovating all the surfaces. On the walls, there is wallpaper and painted textured wallpaper, where the painter has used joint compound and then painted. It has worked well on most walls.
However, on two walls in the bedroom, a longitudinal crack has appeared. In one of the bedrooms, the crack was already there before and has reappeared. How should we solve this? Should we install studs and drywall on that wall? It is an exterior wall (above ground). In the other bedroom, there was no visible crack before, but all the wallpaper was removed as it was loose, and joint compound was applied directly on the aerated concrete.
Now we have torn everything out in the kitchen, the walls are just bare aerated concrete, and now we don’t know what to do with them. We have also made an opening in one wall and recessed a beam in the ceiling for support. We had thought about gluing wet room drywall to that wall because the siporex blocks don’t feel completely stable and to get a smooth wall that doesn’t crack. The painter thinks this seems unnecessary. What should we do with the other walls? We really don’t want cracks to appear in the walls in a few weeks. Should we drywall them as well, or apply joint compound and use something like microfleece? Ideally, we wouldn’t want drywall since it feels best to just have stone walls considering potential moisture problems. If we drywall the other walls, should we use studs on exterior walls, or can we glue the drywall on them? Is it good to use wet room drywall, or is it unnecessary?
We have to decide in the next few days, so I would be really grateful for any information and tips we can get!

Moisture-resistant drywall in the kitchen seems excessive to me, I wouldn't do it. I glued drywall to the wall in the hallway where we removed the walls around the guest toilet, it worked well as a base for wallpapering later.
Framing the wall might be interesting if it's very uneven, but a masonry wall with plaster is usually fairly straight. Not wooden studs in that case, it's silly to mix a material that moves differently than stone/drywall.
Our house is built with siporex and blue concrete mixed.
