ᐅ Ceiling outlets for controlled mechanical ventilation, is that correct?

Hello everyone,
The concrete ceiling needs to be ordered, and I’m supposed to inform the site manager where the outlets for the mechanical ventilation with heat recovery should be.
Originally, 100mm (4 inches) spiral ducts were planned, but this makes the concrete ceiling more expensive, etc...... Now I’m planning to use flat ducts.
The attic will also be converted.
Right now, the plan is for 6 supply air and 6 exhaust air outlets.
Ground floor:
1 exhaust air in the utility room
2 exhaust air (guest WC and kitchen)
1 supply air (living area)
First floor:
1 exhaust air for the bathroom
4 supply air for the bedrooms
Attic:
2 exhaust air (storage room and bathroom)
1 supply air for the room
Does this make sense? Thanks!

Just a quick thought and I’m not a professional:
For nominal ventilation, the mechanical ventilation system should run at about 50% capacity. I would definitely choose a unit one size larger.
Two valves in the parents' bedroom would be better to reduce noise and drafts at high air volume. I’m not an expert either.
Regarding the system, I also asked whether I should choose the larger unit after all. I was told that this one is sufficient based on the calculations.
Regarding the valve in the bedroom, basically there are two ducts running through it and they lead to one outlet at the end. Does that make a difference?

Is that a closed pantry or a counter in the kitchen? If it’s a closed space, then install a vent there. Otherwise, maybe also. At first, it will be my PC corner, later possibly an open pantry or back kitchen.

I think it’s especially important in the bedroom.
Choose a unit one size larger; otherwise, it will have to work harder, be noisier, and may also consume more energy.
