Systems Manager is a funny MDM. Its strengths are iPhones and iPads.
Since there aren't as many best practices established for this, I recommend sandboxing new features as you learn them in the official Meraki training course. (The Udemy ones are excellent too.)
But it also depends on how many employees your company has. In my case, we only have 100-150 iOS devices, to device tags worked well. (I wrote a guide on my SM tagging system here.)
