This is what I want to know; If you get a brand new device and it has FB app installed - but if you never open it or use FB, does that app still monitor things like browsing activity and report anything back to FB?

Aren't android and iOS apps mostly sandboxed? It would be news to me if AppX could access browsing information from Chrome, at least without asking you for permission. Apps can't access folder i/o without permission, surely they can't monitor browsing history without permission.

iOS apps are heavily sandboxed (and given next to no process time when backgrounded).

Android apps are a bit more free, that leads to a lot of apps being good at talking to each other. But the cost is that your sandbox is less sandboxy.

Permissions are a moot point when you're talking about bundled apps because they're already going to be approved for all permissions.
