I guess I can use the regular Apple made Lightning cables on the 2.4A USB charge only port (no data, I wish it did though). Does this make Apple's cables since the iPhone 1 fast charging cables since it can do 5v at 2.4A or this only started with Lightning?
Some terminology: USB is a family of standards, both communications protocols (USB 2.0, USB 3.x, USB4, etc.), and connectors including USB-A, USB-B, and USB-C.
USB-C connectors in particular can be used with very different protocols, including but not limited to USB communications protocols, with USB power delivery protocols, and with Thunderbolt, DisplayPort and other protocols. All USB protocol connections have some power available, but the details will vary.
For USB power delivery, the USB power source and the device negotiate the best available choice for power.
Barring any cable damage or other such cases, any Apple or MFi-certified Lightning cable is utterly irrelevant to iPhone or iPad power negotiations, whether the Lightning cable uses a USB-A or USB-C connector. They all work the same.
This as differentiated from Lightning-related cables, USB-C USB cables (USB-C to USB-C) are available with 60 watts, 5 amps / 100 watts, or 240 watts capacity. The cable capacity is factored into the USB-C power delivery negotiations.
USB-C ports with Thunderbolt capabilities can also deliver power and communications to USB-C Thunderbolt devices, though that requires a USB-C to USB-C Thunderbolt cable.
By the way how about Apple rare, black, braided USB-C to Lightning, what's the amperage of that and how many watts can it take without being damaged?
As much as an iPhone can appropriately consume, based on the available power supply on the other end of the cable.
TL;DR: cables work, or they don’t. It is exceedingly rare to encounter any issues with a cable, absent some sort of mechanical damage, or some cheap junk-grade (uncertified) cables. Cables for different protocols can use the same USB-C connectors, but different cables can permit connections to work, or (with the wrong cable) can block communications. Not working here means not working, and not smoke- or flame- or other excitement-producing effects.
