since this is a long time infrastructure, i would build for more than your current needs, that being said, i would run this if it was my house:
2 CAT6e cables and 1 coax and 1 fiber to EVERY room in the house, even bathrooms and closets (you never know where you are going to put a smart TV or hide a NAS)
in offices and/or studio type rooms i would run an extra set of cabling
i would also run cat6e and fiber up to potential wireless access point mounting locations
that standard is more of what you would call a guideline than an actual rule
