depends if it's a patch cable or running to keystones.
I'd recommend monoprice cat6a 22-23awg, keystones, and patch panel all UTP UL listed CMR.
patch cables don't matter nearly as much. you can buy them premade on monoprice as well or crimp your own cat5e from a long patch cable. if you need 10g get cat6a cables otherwise it's not worth the extra cost. i don't recommend trying to crimp for 10G. if running POE check the cable rating.
which is best networking cable for long term and safe networking
It depends what devices you are networking, how far, where, etc?
If you have 1 GB/s devices then Cat 5e should be enough.
If you have 10 GB/s devices then go up the ladder to Cat 6 (not to exceed 180 ft / 55 meters in length)
Safety is not usually a attribute associated with cables. For home use, cat5e to cat6a solid copper are all acceptable. If you believe that 10GE is a high probability, then cat6a solid copper.
ANY, I mean ANY CAT5e, 6, 6a, whatever cheapest. Just don't buy from eBay unless solid copper specified, lots of fake CCA (copper clad aluminum) floating there.
