Now that I started tearing down the wallpaper, I discovered that all the walls have thin masonite boards, no drywall... I had planned to tear them down to soundproof all the walls... But drywall is much thicker than these, so the rooms will be smaller, and everything just feels messed up...
There is thin renovation drywall, but...
Should I let the masonite stay, is there any advantage to masonite boards at all?
I'm considering letting the ones against the outer walls stay while some partition walls get opened up... but then the question is if I should use new masonite or thin drywall instead... it bothers me that the rooms get smaller even if it's just a few millimeters...

Yes, if you have a room that is, say, 4x4 meters and you switch from 3mm masonite to 13mm plasterboard, the room becomes about 0.016 square meters smaller. Dreadful. 
in the kitchen, I had a large hole, where I could measure a 10mm thickness on the board, though I suspect I might not be so lucky with the others.
People say that "living" material moves more, and it's either because of that or settling that the wallpapers have cracked in some places...

What thicknesses of plasterboard are available?

13mm gypsum is standard, no real reason to take anything else...
Renovation gypsum is only 6mm, though it might work well to place it on top of the masonite...
For an interior wall, you can build with only single gypsum on the framework/insulation, but for better stability and greatly simplified ability to mount cabinets and shelves, you sometimes build with an OSB board under the gypsum. (Strongly recommended for example kitchens...), in other cases, you sometimes use double layers of gypsum.
One of the advantages of gypsum over masonite is its fire resistance...

because the kitchen cabinets etc. hung there... others give a flimsy impression when you knock on them, but then again, they are empty on the inside, so that might be what's giving that impression, hence my desire to open and insulate...
Well, but surely they haven't attached the kitchen cabinets only to the sheet? The reason I don't think it's thinner than 10 mm in other parts of the house is that the entire wall would otherwise sway between the studs. If it's c/c 600 and you have a masonite board at 3 mm, the whole wall will bend just by supporting yourself with your hand.
Have you put up any paintings on the wall? Did the whole wall sway with each hammer blow when you put up your hook?

well yes they are stable in that sense... but it doesn't change the terrifying fact of having to install thicker boards even if the rooms decrease minimally, hehe...
Is renovation gypsum much weaker? rather the rooms become larger..

There was 9mm outdoor gypsum... what happens if you use that indoors? Tempted to rather spackle out that millimeter than to have 3 millimeters too much.
