If I’m reading this right, ars claims that 3.0 is not limited to pro only.

Sorry, you’re not. All models have USB-C connectors, but the non-Pro models are limited to USB 2.0 speeds. The USB 3.2 controller is part of the A17 processor, so that’s why it’s limited to the Pro line. It’ll make it to the iPhone 16 line, though, but for right now, it’s a Pro feature.
USB-C and usb 2/3 are not the same thing. You can have a standards compliant USB-C port shape that delivers USB2 speeds which is what the non-pro has and a USB-C port that implements USB3 which is what the pro has. What arstechnica says is that in bot cases for the Pro and non-pro Apple delivered a standard usb implementation with no additional proprietary requirements
