> Is STM32 still in shortage? In some cases they've never been. It depends on the series. A lot of their portfolio is being made in external fabs like TSMC, whose allocations they gave up when Corona started as they were thinking the chip demand will go down. (Oh boy were they wrong.) On the other hand they still had allocations (in their "own" fabs), so depending on what you want they deliver. Problem is basically anything "mainstream" was in external fabs, e.g. the entire STM32F0 to STM32F4 series. In contrast, if you want an STM32L0 oder STM32L4, you can still order like nothing happened.

Based on what you could buy through distributors, less than 5% of the STM32 lineup is available to buy. The situation was worse, 6 months ago there were 27 variants available on Digikey of the 3000 or so they make. The G series seems to have good availability at the moment, if I was going to bet on a MCU for a new design that would be it. L series has only just gotten better, couldn’t get them a few months ago. Some F3 chips have been looked over (didn’t go out of stock) despite being more advanced than their F4 counterparts. That’s marketing I guess.
