Agreed with csnarpy. While you can get 1, 2, 3, and now 5 Gbps residential internet service through either Rogers or Telus, and most of their gateways have come with 2.5Gbps ports for years now, whether I think most residential customers even
need service that fast is an entirely different matter. Maybe if mom, dad, and all of their 2.5 kids are each streaming a different 4K HDR with DTS-MA A/V stream simultaneously, I could see the need.
Otherwise it's mostly a nerdy willy-measuring contest befitting of the sort of people who would dare venture into this thread -- myself included -- so a little futureproofing to support up to 10Gbps wouldn't hurt.
Izzle: If you're building new, just do CAT6 (or CAT6A if the cost uplift isn't prohibitive). I don't know how big your house is, but my place in Garrison Green was 2,700 sq-ft and the Shaw WiFi gateway was useless, as were the WiFi mesh repeaters that used wireless backhaul. It'll pay dividends to be able to hardwire your meshpoints, and / or be able to hard-wire media-streaming endpoints.
