The only thing that is even vaguely going to approach future-proof is fiberoptic cabling. But you'd spend a fortune in adapters. (Not to mention the cabling itself.)

Cat6a is the highest-spec UTP cable available. (Cat7 is super-shielded. Each pair is shielded and then the whole cable is shielded.) Cat6a was designed specifically so that you didn't need shielding for 10GigE when run in bundles. The next step up from there is 40GigE and 100GigE, each of which are being designed to run only 10m via copper. So unless you've got fairly short runs in your house, Cat6a is realistically the best you can do with copper. Anything faster than that is going to require fiber.
