As far as Apple’s Calendar vs. Google Calendar, Apple’s Calendar is not a factor. I just use my Google Calendar app as my default calendar. On the odd occasion that I need a reminder that is not available in the App, I go to the Google Calendar website which I have bookmarked in the DuckDuckGo app on my iPad.
