I don't see the Zero (2 or 2W) in stock often, but they do come and go.
The model 3 A+ has been in stock regularly now (as predicted in Raspberry Pi's December 2022 blog post), and supposedly we'll get back to regular stock by the end of the 3rd quarter this year for Pi 4 products. Not sure about Compute Module 4... but I hope that too, because it's arguably way more useful.
The RP2040 and Pico have been widely available almost since launch, and in some ways are even more intriguing for educational purposes, especially since they cost $1 and $5, respectively. And the Pico W has been an excellent alternative to ESP devices for ESPHome and other automation needs. The built-in PIO has been a pretty interesting feature, enabling some use cases I didn't initially see.
In the end, I think this year's stock availability will make or break the SBC side of things for the maker / hobbyist community.
There are way faster and more feature-rich boards with chips like the RK3588 at this point, but the software support and available libraries are still leaps and bounds better on the Pi, which is why the nearly 5-year-old hardware is selling at a premium :(
