This mind map was created in an attempt to capture, in an interactive way, ALL of the settings in iOS 11 as of November 2017. There are probably typos and even omissions, and I’d appreciate feedback on them at firstname.lastname@example.org. Note that I will not be updating this as Apple makes changes!
For maximum entertainment at the madness that is iOS 11 Settings, I suggest you start by double-clicking on General, and then Accessibility. There are 281 distinct settings/menu choices inside Accessibility.
For a complete explanation of how I did this and why, please see this blog post: iOS 11 Settings – I Mind Mapped Them All
