I feel confident in saying that I am better at computers than 99.99% of the general population and I have no clue what “SS” or blue USB ports are supposed to indicate.

The USB 3.0 spec was called "SuperSpeed".

The "SS" and blue connector inserts are recommended in the spec to denote 3.0-capable ports.

Apple never followed the spec recommendation because colors and labeling are ugly and for dumb PC users.

Maybe you should reassess your confidence.
