Since I know a few things about this: 1. You probably want to run Cat 6. It’s only a little more expensive than Cat 5e (ours is $180/1000ft for Cat 6 vs $140/1000ft for Cat 5e). The connectors are basically the same price. But Cat 6 will support 10gbps at lengths that cover basically all single family residential. The problem with Cat 6A is that it’s more expensive and doesn’t get you more bandwidth, just the same 10gbps, but to longer distances (up to 100m). Fiber is relatively inexpensive for the cable, but terminations are very expensive and you need adapters for most devices. 2. Don’t buy copper clad aluminum (CCA) Amazon is filled with Ethernet cables that have copper clad aluminum conductors. The reason is that aluminum is cheaper. Don’t buy it. Aluminum is an inferior conductor, but more importantly, it’s a brittle material that will corrode. This is the number one complaint on CCA cabling. That the cable stops working at some point after being installed. 3. Buy cable that is UL Listed/Certified and CM or CMR rated. The CM/CMR ratings are for fire safety and are required to be up to code. Either rating will work, but the key is that the cable has that printed on the jacket. The other key is that the cable is UL Listed/Certified (either wording is fine). UL should also be printed in the jacket. There are lots of Ethernet cables for sale on Amazon that claim to be CM or CMR rated, but they aren’t listed. Which means they’re fraudulently claiming the CM/CMR fire rating because a cable can’t carry a fire rating without being listed. And then you specifically want a UL listing because they’re very active at enforcing quality standards at the factories in Asia, whereas ETL, who is the other major testing lab, is not. There’s a reason that all the cheapest offerings are ETL Listed and all the most expensive ones are UL Listed: basically the factories are sending in one sample for testing and then producing something different. UL’s enforcement prevents this. You might not care about being strictly up to code, but UL Listed and CM/CMR are marks of quality, which you probably do care about.
