Farhan might I ask whi the pico and not just add a pc8575 or pc8574 i2c gpio expander into the mix if you need more gpio.
I think the z2w over pico w is alot better and mre power performance.

The zBitx is called the zBitx because it is based on the RPi Zero 2 W (Zero Bitx), and the RPi Pico W is being added to compliment the RPi Zero 2 W, not replace it.

As for the Pico vs ESP or other microcontroller, I'm not sure there is a significant cost advantage of one over the other (Pico W on a board is just a couple US dollars, how cheap are ESP boards?)
?
I suspect even if there is a greater cost for the RPi Pico W vs say an ESP processor, the engineers/designers may be more familiar/comfortable/productive in one environment vs another, and the RPi Pico W has a lot of interesting capabilities that owner/hackers may be able to exploit down the line.
?
I hope that helps, at least that is what I understand about the selection of the RPi Pico W.
