Cat6a can do 10gb up to 100 meters, which is more than adequate for home unless you live in a sprawling mansion complex. You can also do 2.5gb and 5gb over the same cable.
Theoretically you can do faster (40gb, 100gb etc) over fibre, and 10gb should use less power (although if you have a media converter converting back to cat6 thats a moot point anyway). Equipment with support for >10gb tends to be enterprise/carrier grade meaning it's expensive, noisy and power hungry.
If the cables are exposed, copper cables tend to be a bit more resilient. A sharp bend can destroy fibre very easily.
Generally most consumer devices have copper ethernet ports, devices with direct fibre ports are quite rare so you're better off with copper. Also 2.5g ports are nowadays much more common than 10gb.
I will probably put fibre runs in next time i do a renovation (currently have cat6a), but for future proofing rather than immediate use.
