After moving to a new house (3 floors, approximately 80sqm each, concrete walls), I am in the process of setting up my very first home network (and homelab). I spent a lot of time reading and trying to learn as much as possible, but I still have a lot of doubts and I'm asking for your help before spending a lot of money.

Are there some visible mistakes? Would you change/improve something? Thank you!
