If you want to test bandwidth, that's a five- or six-figure bit of gear.

Why on earth is so much more expensive than an arbitrary pair of devices that could max out a cable?

It’s much cheaper to just buy your cables from Apple or LTT knowing they tested them on a 6 figure testing rig.
I throw out every usb cable that comes bundled with devices because they are literal junk.
This keeps needing to be pointed out every thread this appears on. Plenty of cables have eMarkers that claim "40Gbps" or whatever speeds, or support 240W PD...but absolutely cannot deliver either of those. And none of these consumer level testers can test either of those claims.
Resistance measurements can cursorily test claims of 240W but resistance changes with temperature which changes with current...so unless your tester puts 5 amps down the wire for 5 minutes and then tests resistance it's not a very good test.
