I would look at the issue from a completely different angle.
Instead of investing thousands in different libraries for different sections, I would have a very close look at the following
thread, where fellow members compose music with 1(!) library for everything.
Then, I would pick the ones that I liked most (or suited my aesthetic preferences) and I would buy the cheapest one.
You learn what you like by trying out (or buying) different libraries, so I would suggest refraining from spending thousands at the beginning of your journey.
That way, you can focus on composition without the pressure that all this money adds to the process while having normal expectations from your tools. A 2k USD worth of samples won't make you a better film composer.
My 2 cents as a beginner who fell victim of FOMO enough times during Black Friday.
