You can’t actually delete the native apps, you just get them off your screen and they will be reinstalled when you tap that download icon. Necessary data for the app to function will be retained to be used when the app is reinstalled.

You can completely delete some of the preinstalled iOS apps. For example, the Calculator and the Music apps can be completely removed and there won't be any data left behind.

Just so you know, whenever I setup a new iphone I always delete default apps that I don't need. This is done as soon as the phone is reset into the home screen and before any apps are open or settings are changed.

I have deleted the voice memos app and also the reminders app and they are still showing as having data stored through the iphone storage screen. So it seems that some stock apps will retain data that can not be deleted because I can see you are showing similar to me for those stock apps.

So if the app is deleted before it is run the first time, then the app is completely removed and no residual app data is left behind?

No... There is residual data left behind even if the app has not been run, I never ran the voice memos or the reminders app and they were deleted almost straight after a factory reset. This was on a brand new phone. I must say this seems to only have occured on the reminders and voice memos app for me. Because I also deleted the mail app at the same time along with others and im not showing any residual dual data on that app. So it seems only some apps retain data even after the app is deleted.

Basically the only apps I have on my phone are

* Calandar
* App Store
* Health
* Maps
* Messages
* Phone
* Find My
* Weather
* Facetime
* Calculator
* Camera
* Clock
* Contacts
* Files
* Notes
* Photos
* Settings
* Safari

All other apps are deleted, and the only ones that are showing residual data is VoiceMemos and Reminders... (Reminders may have data linked to the calandar app)

When you deleted the Reminders app did you do that before you logged into your Apple ID? Reminders is tied directly to the accounts you have setup which includes iCloud.
 
before you logged into your Apple ID?
I do not use an apple id nor do I need to download apps or sync contacts.
When I setup an iphone the first thing I do is delete all non needed apps then continue setting up the phone, so the process is erase all content and settings > go through intial steps > once in home screen > delete un needed apps > setup phone as required

You are correct. According to this Apple documen that ability came with ios 14. I think previously the app was only hidden, not actually deleted. But now these shown below can be deleted.

It appears that there is a bug in the ability to completely remove the Mail and Contacts apps that the OP is experiencing.
