Sharepoint online permissions inheritance subsites
Now that you understand how inheritance works, you may want to reconsider your decision to create subsites in the site collection. Many of the new features in SPO, i.e, Office 365 Groups and the soon to be released Hub sites will work best with separate site collections that do not have any subsites.
There are many good reasons to have subsites, but there are also many benefits to having separate site collections. It can be confusing to have a new "site collection" that only has one site (and is not really a collection of anything), but that is just the nature of sharepoint architecture.
I can certainly see the benefit of this flat architecture but it forces you to use the Content Type Hub if you want to create columns and content types that can be used across site collections.
In my particular case I need access to a custom list from several sites (lookup column) and this requirement alone forces a subsite architecture with the list defined in the root site. It doesn't help that creating a subsite from a modern site offers only the Classic site template (I know we can create a modern homepage for this site but it's a fundamentally different type of site)
All very thought provoking :-)
