Which fall protection is suitable for floor-to-ceiling windows? Advantages/Disadvantages

Same here, why should it not. The heat is supposed to stay outside.

Thanks to controlled residential ventilation and the then reversed-functioning heat exchanger (not every controlled residential ventilation system has this), we definitely do not open the windows in the high summer.

We do the same during the day, even with cooling via underfloor heating and air-water heat pump. But at night it is usually cooler outside than inside, so opening a window does make sense. A controlled residential ventilation system does not provide any significant cooling effect.

That is correct. But at night the sun does not shine, which was mentioned here as a problem because of the blinds on fixed elements.

Perhaps one does not want to be woken up by light at 4:30 a.m. Or by street lighting, etc. But as I said, it depends on how sensitive to light someone is.

Then window bars and only open the blinds at night just enough so that the light does not disturb. Or cool the heat away with the heat pump and simply keep the windows closed.

I spoke earlier with a window manufacturer. According to DIN 18008 (VSG(P4), they assume additional costs of about 105 euros per square meter of glass. Whether this is a reliable statement will only be seen when the offer is made. Unfortunately, we have no one in our circle of friends who has floor-to-ceiling windows with [sturzsicherm Unterlicht].
