My Opinion
According to my experience with customers so far, I understood that, there are few points you should always consider before creating your new team calendar. Some of the key points to consider are
- Do you need modern view or classic view? modern view is only available in group calendars.
- Do you have one SharePoint for multiple team? then go with SharePoint calendar as you can manage the permissions individually and target them to appropriate users.
- Do you want to use 3rd party apps to interact or reserve calendar events, then you should consider outlook as it has dedicated graph API. However you can also use SharePoint as SharePoint calendar is a list, which has REST API endpoints.
- If you want the calendar to directly appear in outlook of all users then use group calendars.
