Don’t get me wrong, but it seems like you’re looking for tutorials rather than sources of information.
The FCOM has nothing that could resemble to engineering level details and the information therein contained is pretty much straightforward, this is why you can find tons of other official publications to get into more details. (Flight Operation Briefing Notes, Safety First Publications, FAST Magazine, etc..)
Anyway you don’t really need to get too much into the tiny bits of system details - you need an operational knowledge of the system you are studying in such a way that you are able to interpret normal and abnormal parameters. Throughout the years, you will go over and over the same chapters again and things will make more sense. Try to make the most out of it.
Advice: do not study from other people’s interpretation of the information related to the aircraft, such as all the books and apps you can find online until you have a reasonably good understanding and experience of your own. Otherwise you won’t be able to distinguish rubbish information from valuable stuff.
