My point though was that no one is going to get 40Gbps of speed on a copper ethernet cable. I mean, we are just now starting to get 2.5Gbps nics out there. There is no 40Gpbs copper ethernet adapters out there so it seems silly to market a speed that no one can get.
I agree cuz I am an at&t installer
But if you're rocking some of the new(ish) 1 or 2 Gbps Fiber connections, you minimally want Cat 6 installed, and especially if you're hardwiring anything. Go ahead and go run some speedtests.
Don't take my word for it, you can find all the info you need all over the internet.

You need cat 6 for anything over 1 gbps, up to 10 gbps. I have racks filled with 10 gig switches/servers and cat 6 is great. I only use fiber for long hauls. Traditionally fiber has slightly lower latencies than copper at 10 gig speeds, but the difference shouldn't matter outside of very specialized use cases.... quality cat 5e/6 cables will usually have slightly better packet loss stats because they have better shielding, but again you won't notice in real world, unless you check your hw iface stats. The longer the cable the more important the shielding. I haven't seen any switches/eth cards on the market that use copper for speeds over 10 gig yet, but also haven't looked since my last data center build out and that was awhile ago. It's hard to say whether it will ever be a thing. Also, beware, I've read that some cat 7/8 cables have a special connector that won't work in standardized rj-45 ports, but that was before cat 7/8 standards were finalized. Not sure if standards are final, and what the outcome was.
Edit: I meant SFP not fiber. technically SFP can use DAC cables which are copper.

I was an AT&T tech for over 7 years, did hundreds of fiber installs and techs used what ever they are given you the company. They had not upgraded their bulk cable to cat6 as of a year or so ago when I moved on to another company. However we were using the pre-made cat6 jumpers 4-5 years ago, if your manager ordered them that is.

40gb baseT does exist. You can do interconnect or hook up to supported devices.
40GBASE-T is a port type for 4-pair balanced twisted-pair Cat.8 copper cabling up to 30 m defined in IEEE 802.3bq.[118] IEEE 802.3bq-2016 standard was approved by The IEEE-SA Standards Board on June 30, 2016.[119] It uses 16-level PAM signaling over four lanes at 3,200 MBaud each, scaled up from 10GBASE-T.
I purchased a yet another generic Cat6 cable (with better reviews on Amazon) and I finally get 200 Mbps on WiFi.
So cable quality matters, now if the run was say only 10 ft, I am pretty sure Cat5e would have worked just fine around 200 Mbps, but not if I had internet speed of 1Gbps…
Also, spec compliant copper cabling allows for CAT 5e up to 100m at 1Gbps (2.5Gbps & 5Gbps also possible due to new spec lowering the signaling rate). CAT 6A is designed for up to 100m at 10Gbps. CAT 6 is generally not deployed if 10Gbps support is planned because it's only designed for 10Gbps at reduce lengths (~55m). CAT 6A or fiber would be the preferred choice for 10Gbps.
You had me until you mentioned cat5e.

I have cat 5e in my walls builder installed. I have my own local network all wired and using ubiquity wired and wireless. I'm not an expert by no means but I hit 1gbps speeds locally. My internet I have a 400 mbps line and easily hit that wirelessly on my WiFi 6 router. If you need to do it now and cat 6 can be found for same price then by means do that but no need to rip out cat5e to install cat 6z
