iCloud+
I want to know if I can limit which family members I share iCloud plus with? And do family members have access to my iCloud plus or only the gigs?
iPhone 7 Plus, iOS 15

If you share iCloud storage it is available to all members of your Family Sharing. Family members that are paying for their own upgraded storage plan have a choice of whether they continue with that plan or use the shared plan.
They only share the storage space; they don't have access to your data. See the following from Share iCloud+ with your family - Apple Support
When you share an iCloud+ subscription, everyone in the family group uses their own account. That way your photos, documents, and other information stay private, even though you're sharing access to the service. You simply share the features and space available in iCloud+ with your family members, so you only have one plan to manage.
