Hmm ... I'll explore that.
The USB-A ports I've done have all used the TI power-distribution chips that set the limit at 500mA continuous, with current trip from750mA.

I have a couple of USB-C power supplies that will deliver 3A at 5V or(?) 12V.

The USB 3 Power Delivery spec. says 3A, but if "power delivery" is special, that may explain that. USB has become a bit convoluted and I haven't designed with it in the last few years.
