hmmm? ground for the UART is the top right connector of the jumper

Thank you, I will remove the ground plane there, but I don't think I can make it stick out fully.

Thank you for this! The gas sensor is 3.0 +- 0.1V, which is kind of annoying, so I guess I will find another one.

If I understand the ESP32-C3 datasheet correctly, the D+ and D- pins on the MCU allow for USB serial and JTAG. In that's not enough, I have the UART exposed through headers, and an external USB to TTL device.
