ᐅ Lime plaster and lime paint, or something else – new construction

Hello,
In the new condominium, there is still relatively free choice regarding plaster and wall paint.
On the internet, you often read that lime plaster and lime paint are the more ecological options. However, since the developer wants a price equivalent to that of a new car according to the offer, I’m naturally wondering if it makes sense.
The problem is: this is a new build. Energy Saving Regulation 2014 with heat recovery system. Unfortunately, we have a slight history of mold-related issues... including needing to change wallpapers. Our current apartment is a renovated building from the 1960s. Despite ventilating multiple times, there is a cold spot on an external wall where moisture always accumulates, as well as at the window edge.
Since in the new apartment we will also be cooking, showering, washing, and drying clothes inside, we are naturally concerned that too much moisture in the air will lead to mold growth with standard plaster as well...
So, what to do? Use regular plaster and simply apply lime paint on top? Or rely on the heat recovery system to transport all the moisture away?
The bathroom will be tiled up to the ceiling. The ceiling will be covered with either wallpaper with a raised pattern or painter’s fleece with lime paint.
Please help. Thank you.

Thank you for the information.
Now, moving on. Since the controlled ventilation system with heat recovery is supposed to be very effective, how does it handle indoor laundry drying? We have an interior storage room for this purpose. There is also the option to install a roof window for just under 7,000 euros.
Does that make sense? Or will the moisture generated from drying laundry be removed just as effectively through the heat recovery and controlled ventilation system?

For example, you can only open the roof window in winter and during rain for a few minutes a day at most. In summer, outdoor humidity is often so high that opening it would even be counterproductive.
Since we started using controlled residential ventilation, we have kept all windows closed and only opened them briefly for cleaning. The only exception is the bathroom, where we briefly open windows and the roof window after my wife takes a hot shower for 15 minutes. At that point, the humidity in the bathroom can be as high as 90%.
By the way, we have never used our clothes dryer since the controlled residential ventilation system has been running. It will be removed soon.
Of course, good planning of the controlled residential ventilation system is important. Exhaust air should be extracted from rooms where moisture or odors occur (bathrooms, kitchen, and also a laundry room…). Fresh air supply should go to living and sleeping areas. In our kitchen and main bathroom, double exhaust vents were installed.

Wow, thanks for the great input.
Then we can skip the roof window. The laundry room/guest bathroom can also have windows. My main concern was moisture, but if that is properly vented, the double exhaust should work fine. Thanks.
One more thing about the mechanical ventilation system:
Can it handle odors from the bathroom/WC area as well? I can’t think of a better way to describe it right now, but does it also quickly remove unpleasant smells?
