I'm unsure of the electrical regulations in Norway, in the UK we do not normally have a neutral wire where the light switch is. When your house is wired it may be worth doing this (if not already) to ensure there are plenty of choices with smart light switches.
If I had the chance to build a house, I would be looking to support as much as possible with the infrastructure rather than support for a specific product, in 8 years time you may struggle to replace smart stuff if it's made for certain size or connection.
I have a smart tablet in my wall, but I made the hole bigger than it needs to be in case the tablet dies and I can't find that same size. https://community.hubitat.com/t/in-wall-mounted-tablet/25116
I also think network cable (cat6) is still relevant to every room.
