MS Teams Shared Calendar Best Practices

My company is transitioning over to MS Teams.  I am new to Teams myself, but am well versed in all things Office.  I am a PM supporting 2 consultant groups.  I've started to move my groups over, slowly.  Both of my groups are not terribly thrilled with change, to say the least, nor are they the most proficient in Office.  I would set them at basic daily users.

I will be setting up a shared calendar for each group.  This calendar will primarily be used to track who has what meetings when, so management can track various things such as workflow.

I'm looking for suggestions, best practices, etc. for setting up a group calendar.
