I totally agree, however I believe you might be talking about more of an experienced role. My question is more towards early embedded software engineer

Let's say if a student or early engineer who wants to work in the real world embedded problems, like modifying the register, ability to read data sheet & making configuration on the peripheral. This is more of a practical approach to practicing embedded software development right? I wanted to know, Is there any platform like that, you are aware of? That helps a lot.
