While Google's support documentation currently covers app downloads, Family Sharing will extend to other parts of the Play Store. Previous Android Police teardowns have shown that Books and Movies will also be covered, but there will be restrictions in place to stop the same title being streamed on more than one device at a time.

Although it's not yet known how Android users will opt-in to Family Sharing, Google Music may provide some clues. The streaming service provides a family plan that caters for up to six users, who are invited to link their account by a "family manager." It's likely that Google will follow a similar route with Family Sharing, but include additional checks so that younger users can seek purchase approval for their own apps.
