I am currently working on a <100W system, powered entirely over a single USB-C cable. I'm using this motherboard, and was wondering. In order to replace the DC-in jack with a USB-C female port, would it be as simple as just matching the power pins? Is there any diagrams to STX DC-in pinouts?

You need PD (power delivery) trigger to switch usb-c to 20V. Also your power supply must support PD and use cable capable to deliver 4.3-5A (marked as PD 87W 100W). IMO easy solution is to use PD adapter type-c to dc 5.5x2.5mm:
