Their FAQ is definitely unclear, but, as mentioned in a previous HN discussion, a 5V/3A is going to work fine for most workloads. They limit downstream USB current to 600mA. If you need the full 1.2A limit, you can buy their power supply, another (not common) one, or a powered USB hub.

5V/5A will also give you 5W extra power on the device for their high performance mode.

But again, it’s not necessary and most uses of a Pi will do fine with 5V/3A.

I don't think so. Historically, Raspberry pi board always had non-standard power requirements and always required rpi's official power supply to work reliably. My RPi4 board forced me to buy the official power supply to work without weird problems and I did nothing but vanilla stuff with it.

RPi5 worsens this problem by requiring a power supply that draws 5A.
