Hardly any of these cables are labeled properly. Even Apple has a Thunderbolt 3 and Thunderbolt 4 cable that it sells for $150 without any difference in the labeling.

Is there a difference from the cable point of view with thunderbolt 3 vs 4?

Let's put resister color codes on the wires, 2 sets of 3 bars (digit digit exponent), 1 for megabytes and 1 for milliamps. So red black yellow space green black red is 20 gb 5 amps.

Great idea! But what to do if some jack manufacturer will take a beautiful cable and waste it with an awful jack for the sake of some economical reasons?

I have many USB-C cables; zero of them are labeled with those icons.

Also that list excludes the thunderbolt versions which have a thunderbolt and a number.

There are some cables that show the power throughput [1], I would like to see cables that show data throughput as well.

Ah, you need the scratch and sniff version of this card. My only complaint is how subtle the difference is between between the smell of the 45W fast and regular charging cables.
