Well, it is above all also the way to the kitchen, the children's rooms, etc.
Way to the kitchen in the morning... and almost all of it is also to get every schoolchild to the door. You can’t even quickly call up the stairs from the kitchen that it’s finally breakfast time, etc.
Sofa with its back to the window, but always nicely facing the hallway.
-------------------------------------------------------
For example, children's room 2 from your sectional drawing:

do you see what I mean? As a rule, you don’t open a door completely to go through, but already go through slightly at an angle... and here you end up at the sloping ceiling. Because the yellow is the door to the children’s room.
-----------------------
Upper floor... just the stair landing situation:
rather narrow and dark.
For this one here:
open space, the south-facing window. At the bottom of the plan in the north then the storage area for the floor vacuum cleaner and mop.
Storage space in the bathroom for towels, toilet paper, etc. and a really large shower without a sloping ceiling.
Additional storage space in the hallway, e.g. bedding in the dressers under the roof window. Ok, the dressing area now has a little less storage space upstairs due to the sloping ceiling than in your last version, but on the other hand additional practically distributed storage space.
Furthermore, your upper floor covers 2 steps of the stairs coming from below. Unfortunately, this is not included in the section, but it could restrict headroom on the stairs, especially when going down.
