When you share a storage plan, your photos and documents stay private and everyone keeps using their own accounts with iCloud—just like when you have your own storage plan. You simply share the space available in the iCloud storage plan with your family members, so you only have one plan to manage.
You can of course still share data in the same ways that you could if you were not sharing iCloud storage. See: Share folders with iCloud Drive - Apple Support and How to share albums in Photos on your iPhone, iPad, and Mac - Apple Support

Can family sharing members of iCloud storage see or access each other's files?
