When I first ran ethernet in my house, 21 years ago, I ran Category 5e. 1 run to each room. 10 years ago I started a structured wiring project, 24 gigabit ports + Access points with additional ports (routers). I repurposed the Cat5e for VoIP, and ran Cat6 as it was literally a dollar a box more than 5e.
I have gigabit internet service and honestly it supports everything I do, including more or less 24x7 streaming on multiple devices with LOTS of headroom.
I don't see a need for anything faster than gig in the foreseeable future, however new technologies can change that in a hurry just like streaming video did.
The problem I would have with anything newer than cat 6 is backwards compatibility with Fast, and gig ethernet devices which I still have in abundance in the house.
So for me, and my applications as far out as I can see, Category 6 is more than enough. HOWEVER, I did run the cable so that back pulling newer cable would be a negligible effort...
Do what you will, how you will, but I made my choice and am happy with it.
