Like Curtis, I received le formal CS education, so I don’t know of any good resources for autodidacts outside of the textbooks. IMO there’s no “fast way” without missing out on the foundations, you have to learn the above topics in some depth or you will hit limits and problems that you do not understand.
Do you have any recommendations as to books/youtube channels/classes in, say, the OS department?
I learned OS from the good old Tanenbaum: https://en.wikipedia.org/wiki/Modern_Operating_Systems
