New fan: Gonna read the manga and novels soon so I need help

I watched the 1st 3 seasons of the anime (not movie yet) and now watched the 1st episode of Season 4. Awhile back I tried to read the manga from where S3 left off but was busy but S4 E1 isn't the same 1 I read. Found out there was light novels that were adapted (cool, more content and makes certain arcs make sense in retrospect) but wanted to understand the order of everything up to S4:

For eg:

• S1: What manga chapters and what light novels are adapted (including which episodes)
• S2, 3, movie, S4: Same thing, etc etc. So a general reading order/ breakdown when I'm done with exams so I can catch up would be very helpful.

Thank you in advance.
