You could use right angle headers tack soldered to the top, but they'd project more. If you connected with wires you could use a smaller connector than 0.1" pitch, like 1 mm. You could have the connector come out a side slot. It might also be that the Type C connector has Alt Mode for debug.
On my Poke3 the kernel doesn't have the serial driver so there's no Android console. There were holes in the board, but the tolerances underneath are very tight. I soldered in the connector then filed the pins and solder almost flush.

Interesting for sure.
I didn't remove the USB port, but I'm pretty sure there's no speaker underneath as that corner isn't magnetic. So maybe lining up a female PCB socket behind those holes might be a good idea. That way you could just stick pin-headers trough the speaker-holes. (If there's enough clearance underneath.) You wouldn't even see any modification from the outside.
The bread-board you use in between is so that it could not damage the hardware in case you switch up TX and RX?
