Create wiring/electrical plan for a single-family house!

Hello, I was wondering if there are any wiring diagrams or sample electrical plans for a two-story single-family house?
I will soon be doing an electrical installation in a single-family house but I am not yet sure how to handle the cable routing. I have already marked switches, sockets, and light outlets on the floor plan but haven’t progressed further.
I want to design it so that there is a single electrical distribution board on each floor. Is a 5x6mm² cable sufficient running from the bottom to the top? Will the cable at the bottom then be protected by a 32A fuse?

Best regards, Ronny

First of all, you will hardly find sample plans that could really fit. The standard with the installation zones, which also applies to do-it-yourself, must be observed.

Topic UV on each floor
Well considered,
However, the protection and cross-section can only be estimated since the cable length and installation method are unknown.
A 5x6mm² would be possible, whether with 32A pre-fused must be calculated. The protection must also match the main fuse, topic selectivity

Let a specialist handle it, or at least get advice from [this]. Who will accept the system later and sign for it? That person should also answer your questions.
