What do you want to do with it?It looks using a USB C port is going to be a pain, I was looking of a USB 2.0 only port that had just the power and data lines turns out this is not as simple and this type of port has 8 pins broken out? Micro USB seems like a much easier to use connector and hand work.
Using a USB-C connector for power and the RP2040's USB port is easy. It just requires two extra resistors (5K1 from CC1 to GND and CC2 to GND. CC1 is pin A5 on the connector, CC2 is B5), and you need to wire the USB and power signals to two pins on the connector in parallel to tolerate the connector being plugged-in either way up. So USB D+ is pins A6 and B6, D- is A7 and B7. VBUS is A4,A9,B4 and B9. GND is A1,A12,B1,B12. SBU1 and SBU2 can be left open (pins A8,B8).
You will find that the connectors are made in two versions - one with all the pins connected (so you can run USB3 etc over it), and another version that only has the pins you need for USB2 (ie. the pins I've listed above). The ones with fewer pins are slightly cheaper and easier to use; some of them are quite OK for hand-solder (better in that respect than some micro-USB I've used in the past).
