I lost my thunderbolt cable for my ASD. Can I purchase a 3rd party cable off Amazon or do I really need to use Apple's ridiculously overpriced one?

For example: https://www.amazon.com/gp/product/B0C4JNTTNY

I know a 3rd party cable will work. Just wondering if there's any benefit to Apple's?

Where cheaper cables may fail (especially long ones) is the bandwidth supplied to the USB-C ports on the monitor.
Some will do the video well, but only manage USB 2 speed to the data ports.
 
Find any certified Thunderbolt 3 or Thunderbolt 4 cable, it doesn't have to be the Apple one. But as stated previously, do not buy any USB-C cable, it has to support Thunderbolt
 
A USB-C charging cable is limited to USB 2.0 speed (480 Mb/s) and won't work with a display, but a USB-C data cable (10 Gbps) can support Thunderbolt at 20 Gbps. That is sufficient for Apple Studio Display or Apple Pro Display XDR if your GPU supports DSC (15.4 Gbps for 6K60 and 11.2 Gbps for 5K60). Verify the connection speed in the Thunderbolt tab of System Information.app. Max USB transmit speed (10 Gbps for the USB ports of the Apple Studio Display and 5 Gbps for the USB ports of the Apple Pro Display XDR) will be slightly reduced but USB receive speed should be mostly unchanged.
