What areas should be addressed in Office 365 Governance Plans?

Office 365 Governance is an area that has as many definitions as the number of people you ask about it. I have updated my blog with a https://providing.tips/2019/08/12/what-areas-should-be-addressed-in-office-365-governance-plans/ where i, based on my definition, compiled the points/areas that I consider to be important to start with when establishing Governance for Office 365 and its services.

I am interested in getting suggestions also from you on which areas that are most important for you to have control over in order to be comfortable and satisfied with the administration of your environment?
