ᐅ Interior Insulation for a Mid-Terrace House: Flooring, Ceiling, and Soundproofing

Good evening,
In an apartment (ground floor, with a total of three floors plus a basement) in a mid-terrace house, I want to insulate the exterior walls. The outer facade is plastered. Adding external insulation is not an option and will not be changed.
Above the apartment is another apartment. The ceiling is a timber beam ceiling. Below the apartment is the unheated basement. A concrete ceiling is installed, on top of which a wooden floor is laid. The exact layer structure is not yet known.
The apartment has exterior walls on both long sides. The apartment door opens into an unheated hallway. The interior walls are about 12 cm (5 inches) thick and plastered. A fine plaster finish has been applied.
The walls need to be redone because the fine plaster is not liked. I want to avoid completely replastering with removal of the old plaster first. Therefore, I am considering gluing drywall panels (e.g. gypsum boards) to the walls. In this process, insulation could be installed as well, but it should have minimal thickness.
The following questions:
1. How can I insulate the exterior walls from the inside? Which insulation material is recommended to keep construction thickness as low as possible?
2. What should be considered regarding vapor permeability?
3. How should the connections to interior walls, ceiling, and floor be executed?
4. Does it even make sense to insulate a single apartment in an existing building? Or is there a risk of damage occurring in neighboring apartments that are not insulated?
5. How should I deal with window reveals, considering that the reveals above are designed as arches?
How should I build up the floor to improve insulation and soundproofing?
How should I insulate the ceiling to also achieve a higher level of sound insulation? The apartment is extremely noisy. The floor of the apartment above does not seem to be decoupled at all, probably planks on the beams without impact sound insulation.
The ceiling height is quite limited at 230 cm (7 feet 7 inches). So, there is not much space available.
Best regards,
Frank

Please don’t forget that drywall panels also require a considerable amount of work if you want a really good finish. I don’t really believe it’s easier or faster than applying plaster over the masonry walls.
To achieve a truly smooth drywall surface, as far as I know, it needs to be filled and sanded about four times.
That is quite a significant effort.

I’m quite comfortable working with drywall and have some experience with it. It would be glued to the wall, the joints filled – that’s it. Then a textured wallpaper (woodchip wallpaper) will be applied and painted once. I can reasonably estimate this effort. As for plastering the walls, I’m not really confident… ;-) and it should look good after all.
By the way, the ceilings are covered with paneling – very much late 1980s style. Although I’m a big fan of wood, the ceiling wood has to come down as well. The ceiling will also be covered with drywall.
And then the floors – there’s quite a lot to do. The 1950s bathroom will be renovated too. You’ve got to keep busy somehow.
