We are in the process of renovating a couple of rooms. All wallpaper has been removed and the walls have been skim-coated (not sanded yet). Now they will be painted and the plan is to skip the ceiling trim and go for a so-called "snobbrand," i.e., paint the ceiling color a few centimeters down onto the wall.

The walls are gypsum, and the ceiling is made of some kind of board. On most walls, the gap between wall and ceiling is fairly tight, but on some walls, there is a significant gap, see images below.

My questions now are:
1) What is suitable to use to fill the gaps?
2) I have read that people usually apply a paintable caulk as the final surface. What is used for that?

Gap between ceiling and floor
A gap between the ceiling and unfinished plastered wall is measured with a ruler. The gap is approximately 1 cm wide. A gap between a ceiling and a wall with a ruler showing the width of the gap. The wall is plastered but not yet painted.

Wall without a gap
Gap between ceiling and wall with visible plaster on drywall in a renovated room, awaiting painting and filling with caulk.
 
I use caulk/latex caulk in quite a few cases. But it's unclear how well it works to really paint over such a wide joint.

You can always fill it in with putty as best as you can, then use tape and smooth it out again. But if you're going to extend the ceiling paint a bit onto the wall (assuming it's white), you might as well paint it the way you want it and fill in with caulk afterward. Provided you smooth/level it along the entire way. If you use caulking tools that make the joint smooth and neat, it shouldn't be noticeable. If the wall/ceiling moves and cracks appear in the caulk, making it easy to switch to a ceiling trim instead. It's important to use good quality caulk that doesn't yellow, that's really the only thing.
