Any Ethernet cable is rated to 100m (328 ft) maximum for runs. As far as speeds go:
Cat 5/e supports up to 1 Gbps, which is what most consumer networks run at.
Cat 6/a supports up to 10 Gbps, with the primary difference being that only 6a is rated to 100m for 10 Gbps
Cat 7 really isn't used
Cat 8 is being designed to support 40 Gbps
