How do I consolidate all this at this point: Icloud Drive, Itunes Match, Local iTunes Library, Local iPhoto, Local Aperture, Photo stream, Familly sharing, sharing on iOS, music sharing on iOS, music sharing on mac etc.

Question

I am trying to grasp all the possibilities for consolidating my stuff and my family's stuff from multiple devices and multiple accounts from multiple sources  but I cant. 
I have been reading many instructions and FAQ regarding iCloud Drive, iCloud Sharing, iTunes Match, Familly Sharing, file size limitations on iCloud Drive, app sharing on iOS, Backup vs Sync vs cloud sharing,  storing iWork documents on iCloud drive, storing iTunes library on iCloud Drive, storing iPhoto library on iCloud Drive, storing Aperture library on the iCloud, the Photos app on iOS with iCloud and many others.... but I feel like I need a systems admin course from apple to manage all of it.
This is what I and my family currently have:
Hardware: Multiple iPhones, Multiple Macs, Apple TV (with hard drive), Multiple iPads.
Operating systems: Everything is upgraded to the latest iOS and Yosemite.
Libraries:
1)  Multiple iTunes Libraries locally stored on Macs and IPhones with lossless CD music and iTunes purchased music. What I want to do:
a) Have a main family shared iTunes library across ALL devices that contains our Lossless music and purchased music. so that it can be played across ALL   devices. With the ability to have private music for each individual (Not shared).
b) Purchase new music and add it to the family share or purchase music and make it private (Not shared).
2)  Multiple iPhoto Libraries macs (With photo stream from iPhones) and ONE Aperture Library on my mac. What I want to do:
a) Have a main family shared photo library that every one can deposit to and view.
b) Store individual iPhoto libraries on iCloud Drive(s)? So that everyone can have their own library and edit it across THEIR devices.
c) Store and use my Aperture Library on iCloud Drive?
Other documents:
iWork files, PDFs etc. What I want to do:
a) Have a main family shared area (on iCloud Drive i suppose) where we can share documents.
b) Sync private documents across ALL individuals devices (Available locally and on iCloud).
c) Store private documents (One instance)  on iCloud drive and make them available on ALL individuals devices.
d) Backup of local documents?
Apps:
iOS apps:
a) Share purchased apps?
b) Not share private apps.
Storage:
What do I purchase to accomplish the above:
a) iCloud storage for everyone?
b) iTunes Match for everyone?
c) All of the above?
Conclusion:
It would be great for Apple to explain all this with all the options in one concise document instead of hunting down individual documents and sections all over the place.
Thank you for your help.

Hey there!
You and I are data soulmates. I have been having this trouble for a while and have yet to get my head around it. Our problem is that we've cycled through multiple macs and the "home" or "host" for all the stuff that's now been moved or moving to the Cloud is very scattered. It drives me crazy... almost to the point where I'm thinking about starting a brand-new iCloud account and beginning from scratch.
If you have any experiences or recommendations you could share about your strategy, I would love to hear it.
