For a good practical guide on switching regulator component selection and layout check out Phil's Lab on YouTube:

He also has good guides on digital audio processing and sensor fusion.

His videos definitely helped demystify my prior assumptions about how to incorporate ESP32s or STM32 in my own custom PCB designs (and not deal with external programmers, castellated edge ICs etc or resort to devkits adding quite some vertical space requirements and coming with issues of their own).

Highly recommended channel.
