Surprised at all the recommendations for Cat6. That’s fine for Gigabit. Houses are already being serviced by fiber with speeds that exceed Gigabit speeds, so the minimum I would suggest in 2023 is Cat6A.
I am currently in the same situation but missed the wiring deadline so I am going to end up running OM4 fiber (10/40/100 Gigabit) under carpets for the office/living room/bedroom. Small SFP+ switches are available for reasonable prices now, so you can have a fast 10Gb trunk to service each floor and take 2.5Gb from them.
That’s correct Cat6 maxes out at 10Gb on short runs. It’s also a case that there’s an issue with heat, trying to push 10Gb over wire - usually exhibited in the SFP+ transceivers, switches and such, which is reduced with 6A and better.
In 10 years time, will you wish you had made the minimal additional investment in 6A over 6 when speeds increase and your wires are all behind sheetrock or plaster? I’ve already done multiple build-outs in commercial and homes, and I’m well aware of how quickly these wiring jobs become obsolete. So I won’t even touch anything below Cat6A today.
Addendum: the heat issue that causes 10Gb copper wire SFP+ transceivers to burn out is why I’m running fiber - significantly cheaper running costs too.
