You actually can run 10GbE over Cat6 and 8P8C ("RJ45") connectors if you
really want to
(https://en.wikipedia.org/wiki/10-gigabit_Ethernet#10GBASE-T).  So yes,
Cat6 up to 55m, or Cat6a up to 100m should be good up to at least 10GbE.
 It's not completely future proof, but it'll be pretty good for a while.
 10Gb/s should be enough for anyone, right?

The switches are very expensive right now, though, and the switch
latency is higher than the SFP+ 10GbE solutions, since the line
encodings built into the 8P8C PHY are much more complex than those in
the SFP+.

I agree that, especially in a residential application, fiber doesn't
make sense yet, possibly not ever.  But Cat6 might also do better than
you thought.
