I would run Cat6a if I was building a house, because it's the latest spec and not much more expensive, but Cat5e is still great. Standard WiFi never gets anywhere close to those speeds, is simplex, and I find a 10Mbps Ethernet (powerline) link handily outperforms a 100Mbps WiFi connection for networked file system access. (Probably either an issue with the simplex or dropped packets)
P.S. Cat5e can still do 1Gbps, just not over quite as great a distance as Cat6. Although Cat5e definitely isn't rated for 10Gbps (nor is vanilla Cat6 for that matter)
