Meanwhile, there are some useful-looking links here:
pico sleep mode via micropython

Hmm, I'm not so sure. the RP2040 datasheet

https://datasheets.raspberrypi.com/rp204...asheet.pdf

has the power consumption and the lowest it seems to go is 100's of uA. That's OK if running off a DC supply or a big battery but if you are trying to run off a 2032 battery with, say, 100mAh or even 200mAh then it starts to be a problem.

Maybe I'm not reading that section correctly?
