Verified compatibility answer

Is the USB-C cable included with Pixel 9 a USB 3 cable?

No. Google's Pixel cable documentation identifies the USB-C to USB-C cable supplied with the Pixel 9 family as a USB 2.0 cable. A faster phone/host path therefore still needs a separately suitable high-speed cable when the use case requires it.
