• Adafruit Pico version bill of materials
• For mounting (all versions), thick sculpting wire wrapped around Stemma-QT cable
• I ordered 5 Pico W's with unsoldered headers at PiShop instead of Adafruit (out of stock)
  • I couldn't find a solderless JIG for the Pico W, but maybe someone will come up with one eventually
  • When the Pico WH is available (and assuming it can be sourced), this is the preferred option
  • The Maker Pi Pico is a version that comes with the Pico directly soldered on, but this didn't seem to be in stock, and I'm not sure if it would come with the Pico W

The key difference in the switch from RPi Zero 2 W to the RPi Pico W is the Blinkt! module has been replaced by a single NeoPixel LED on a Maker Pi Pico base. The Maker Pi Pico base has Grove ports instead of Stemma-QT, so a Grove to Stemma-QT adapter is included in the parts list. 

Maker Pi Pico has an example script for the NeoPixel LED. Setup for the Pico can be found in this Adafruit guide or similar guides.
