What is always right is what the woman wants. Period.
Fortunately, my wife wanted textured plaster. Yes, we already have a few traces of a spontaneously organized knight tournament in the children's room (we have decided on wallpaper there) as well as in the hallway and on the stairs – these can be surprisingly well repaired on textured plaster. I also have a spot here that was repaired during construction (the electrician was looking for a flush-mounted box with a hammer after plastering, the missing plaster cover tabs could have told him that there isn’t one, but he gave up only after 10 minutes) and you really only notice it if you know about it.
As a child, I was allowed to choose the wallpaper for my room myself – I was six years old and liked the Smurfs, so it was Smurf wallpaper. Not only was Smurf wallpaper extremely uncool a few years later, but it was also plastic-coated and therefore extremely ugly to remove. Just as permanent as the wallpaper were all the scratches in it. God, I was so glad when that shame that prevented visits from girls was finally removed and replaced with textured wallpaper.
Therefore: textured plaster and then stick on. With pictures from kindergarten or the fan poster or whatever. But it is really quickly removable.
