Groups are used for configuration of APs/Switches/Gateways and sites are used mainly for visualisation/reporting/monitoring based on geographic locations.
So as long as the devices have the same configuration (more or less, you can get ways with having one group.
Realistically if you have a lot of sites, they could be categorised by size like small/Medium/Large and most likely, they could have different configurations and hence the use of different groups.

Subject: Central best practices
Are there best practices for Central for example how to group different devices? As you can't move/copy roles between groups, is the idea that you only create a single group and then put 2000 APs and 2000 switches in the same group even if they are in different sites?
