I will give the options some hands-on consideration - including component specifications- because I have something in (slow) work that uses 3.7 LiPo on solar cell with charge board and powers some sensors, LORA and PICO / Puck. For the nMosFet option I plan to use @DrAzzy's nMosFets - see conversation about Power Supply. I had them already successfully in use with a Espruino-Wifi and LED light panels... LED's feed by 5V and low-side switched.
Espruino is a JavaScript interpreter for low-power Microcontrollers. This site is both a support community for Espruino and a place to share what you are working on.
@Gordon, something like that:
(Optional) RESistor3 helps smothing ripples and decouples the voltage divider even more.
I had some concerns for the reliable switching of nMosFet as well, as you documented on https://www.espruino.com/mosfets and @DrAzzy points out in a post of this conversation about ...PICO ... and MOSFET.
