Well, USB-IF made a mistake with USB High Speed, Super Speed (+), Full Speed.
Since 3.2 it was pretty simple:
- SuperSpeed USB 5Gbps
- SuperSpeed USB 10Gbps
- and so on.
However, to use, those vendors must send devices for testing and compliance. Many just don't do certification because they don't want, and some don't do that because they're making straight up non-compliant: SuperSpeed USB 20Gbps a.k.a. USB 3.2 Gen 2x2 can only come in USB-C form.
USB 3.2 Gen 1x2 which has the same speed as USB 3.2 Gen 2x1, but it only comes in USB-C unlike USB 3.2 Gen 2x1. When you see a motherboard with USB-A ports and those specs - those are not certified.
Then Super Speed branding tells you nothing about Power Delivery.
