The rp2040 is cheaper and probably better for teaching embedded electronics. (and super easy to get access too). It's documentation shits all over the ESP* tool chain, and its a nice, smooth coherently documented ecosystem.
I understand that you want the pi-4, as do I. But. The money from pi sales goes to education, you can see it in the company accounts. The documentation, and family of hardware is unparalleled anywhere (outside maybe adafruit)
The world is complex, and sometimes doesn't do what you want. Don't shit on something because you're upset that they aren't doing exactly what you want.
