Look for Cat5e plenum grade cable with molded connectors. Do not use any hand-made connections unless you have them tested. There is a lot of quality loss in the connectors... but not much difference in the cable, though the big difference is between solid core and stranded wire.
Solid core is far the best, but has very little flexibility.
If the cable is rated at 1000-TX, 350Mhz, 24AWG, with solid copper connectors, you are getting what you need. Gold plating is a plus, but be sure it is quality gold plated stuff, or you are just wasting your money.
Hand-crimped connectors is not nearly as good, as machine crimpted then rubber molded.
There are several good brands available with a Gurgle search.
