Man's unfailing capacity to believe what he prefers to be true, rather than what the evidence shows to be likely and possible, has always astounded me. We long for a caring Universe which will save us from our childish mistakes, and in the face of mountains of evidence to the contrary, we will pin all our hopes on the slimmest of doubts. God has not been proven not to exist, therefore he must exist. -Academician Prokhor Zakharov, "For I Have Tasted the Fruit"

Well the way I see it, you can theoretically have one cable and one plug to rule them all (ie a cable with all capabilities). The problem was always that no one wants to spend $130 on every cable. Like if I buy a mouse for $100, but the cable to charge it now has to cost $100+ in materials, then would I really want to spend $200 on the new mouse with USB-C if it was imposed on me to have TB3 and 100 watt charging that the mouse doesn’t use?
So whatever was going to happen, there are simply constraints due to materials cost, due to the fact that some devices don’t even use higher speeds for anything, etc.
And that’s interesting about the cable/device problem you’re having. I would think that should be impossible. Are you using the 2m or 1m Apple Thunderbolt cable? Either should be fully capable of 10 Gbps transfers, as either is capable of 40 Gbps for Thunderbolt devices. It perhaps could be due to the devices you are using and not the cable. Or some combination. But I had not heard of that and I had no problem with the Apple Thunderbolt cables and gen 2 USB devices.

3.0, 3.1 gen 1, and 3.2 gen 1 are the same thing, 5 Gbps USB data but with minor changes that don’t affect the user (ie, you need 3.1 at least to use USB-C with Superspeed data rates).
Similarly, 3.1 gen 2 and 3.2 gen 2 also refer to the same thing. 3.2 only really added new data transfer speeds that aren’t used widely and still are outpaced by Thunderbolt 3 anyway (3.2 gen 2×2 is the main new transfer speed at 20 Gbps). Most devices will never even see gen 2×2 because Thunderbolt doesn’t seem to support it, you have to add in a PCIe card with gen2x2 support.
So really you have 3 things there, 5 Gbps USB, 10 Gbps USB, and 40 Gbps Thunderbolt. Slightly good news: If you have Thunderbolt 3 you have all of the above. Slightly bad news, if you don’t have Thunderbolt you have to check spec sheets to figure out what a USB-C port can do.
Cables have different charging capabilities, but there really is only a few classes of charging cables: 3 amp, 5 amp, and the new EPR cables (not currently available, even the Magsafe 3 one terminates in Magsafe 3 and not USB-C). 3 amp = 60 watts, 5 amp = 100 watts, EPR up to 240 watts. It’s more up to the charging brick and device to figure out what amount of power can be allowed than the cable, up to the limit of the cable.
