You speak into one end and calculate the time it travels to the other end.

Throughput test with a tool like iperf3.
Not even close.

So do you use their app or a software? Is it free? Is there any tutorial on it?
It is free software. You can run it on Windows and Linux. It's a pretty simple command line tool, I think you just need the -s flag for the receiving side and -c for the sending side. Yes, you need to run iperf3 on both ends, so you will need two devices.
CAT7 and CAT8 are loose standards, so the answer is yes and no.
CAT8 is rated to carry 2000Mhz over 36m, which isn't a significant feat anymore with how well cable production has gotten. There are plenty of overkill CAT6A cables that can perform just as well by this metric.
Assuming you're only interested in the 40Gbps metric, then no, this isn't going to come close.
Though it's also important to note that anything above CAT5e is always going to be a crapshoot, especially when taking it over long runs. It's also largely dependent on your hardware.
There's certainly nothing wrong with using CAT7/8 even for lower bandwidths, as they're inherently built better (more EMI shielding and twists) and don't cost significantly more, aside from the fact that they're more delicate and thicker (thus harder to run).
But if you really need 10Gbps or better connections, you should be using fiber.
Just stick to cat6/6a depending on your need.
Nice!

CAT7 isn't standardized and fully certified (it overlaps with CAT6A), but CAT8 actually is.

You cannot test if something is rated for 40 gigabit if you don't have 40 gigabit network hardware.
You also can not have 40 gigabit hardware that doesn't use fiber optic cable (an entirely different connector altogether from the "Ethernet" that everyone usually thinks of).
Either way, I got a bridge to sell y'all if you are interested.
