Wondering why a default alert time set on one device doesn't synch to the other device. Seems like it should (future upgrade?). Looks like you have to set a default alert time one time on each device. However, if you set a non-default alert time for a particular event, it does synch when using iCloud to synch between them. Using the latest iOS 16.03 and macOS 12.6 at the time of this writing.
MacBook Pro 16″, macOS 12.6
The calendar does not sync between devices. All the devices sync with the email client server which hosts your calendar. Add the email account which hosts your calendar events in all the devices .
Where are the calendar events stored on your iPhone? Please add the email account, that's it.

When you add events to the Calendar it gets added to the Default Calendar set on your device.
