Competent using the Cube MX graphical config tool

Don't consider these tools as learning tools. It's just pin planning and initial config of peripheral blocks.

Look for STM or independent tutorials/videos/... on that stuff. If you use a specific board/I2S peripheral chip, this will also determine your configuration.

The firmware repos might also have helpful sample code.

This must be individual.

For example, there are people who consider video tutorials useful. I am completely unable to gather any technical information from those videos. OTOH, I have no problem reading and understanding written and illustrated text.

This is probably why I find CubeMX mostly useless, as it's good only to "connect prechewed blocks", and inevitably fails to convey any more nuanced details or teach underlying principles.

I don't say it's impossible to make a truly informational video, or to make a useful clicky; but it takes several orders of magnitude more effort (read: people and money) than just recording a lecture or slapping together a couple of blocks in your favourite PC visual programming tool. And there's simply no market for that, nobody is willing to pay the price.
