ᐅ Is a fine plaster finish (Q2 lime-cement or gypsum) sufficient for living spaces?

Hello everyone
I am currently trying to familiarize myself with the topic of house construction and keep coming across some confusing questions. For example:

I have a building specification that states all living rooms will have fine plaster (quality Q2 cement-lime or gypsum plaster) applied to the walls. Nowadays, it is common to use plaster instead of wallpaper on walls. Would this type of plaster be suitable for that purpose, or does it require additional treatment, such as a different kind of plaster? Or does it definitely need to be painted or wallpapered afterward (the walls are intended to be white anyway)?

If a different type of plaster is needed, can it be applied directly, or does the fine plaster always have to be used as a kind of base coat?

We can live well with Sto Sil on Q2. Seriously, even our guests don’t notice anything negative. As I said, we didn’t just roll it on lightly; my brother went ahead with the lamb’s wool roller, applying it generously. I followed behind with a ceiling brush and wiped large semicircles into it. Since the material contains grains, it intentionally looks uneven. My brother says architects love this; they like to specify it, and then the painter charges a premium for a job that any experienced craftsman with an apprentice could do. Try it in the basement, and I’m telling you, it will catch on.

I once mixed quartz sand into paint and applied it with a brush to texture the wall. Would that create a similar effect?

Then I have to say: the fine quartz sand looked much coarser than the "sample" currently shown here at Q2.
I missed the quartz sand back then, but now I am satisfied with Q2.

Hmm, I have a wall with quartz sand, and it looks much coarser than the Q2 finish the general contractor delivered...

Exactly like that.

Phew, then I probably received better quality than I paid for... my Q2 is significantly smoother.
