CanBus
I got an OBD2 extension cable with 90 degree ends to make a low profile connection. I cut the cable in half. (Photo!) Now I have a connector with a 12" cable ready to use.

I don't think I need termination as long as my cable is less than 0.5m long. (It was 18" but I snipped it down to be on the safe side.)

MCP2515
Seeed Xiao
I intend trying this one first because it's got a more commonly used chip on it.
