(Update 11-13-2023) Migrated most everything. The sticking point is the Microsoft Authenticator app (for work and school), and the RSA SecurID app (for work).
For Microsoft Office 365 etc., I found this link is important and useful. It will save the user some trouble and basically it will allow the use to self serve (setup the app on the new device). The trick is to add the phone (text message) number to the account, before deleting the authenticator app on the old iPhone and on the myaccount.microsoft.com web page. Deleting it from the web page and re-add the authenticator app will prompt the user to scan the QR code and setup the authenticator on the new phone. Without adding the phone number, we will likely need the help from helpdesk (they will need to do a reset of the Microsoft account). I did this successfully for two accounts (out of 3), and I messed up another one and had to get help from the Helpdesk (basically they need to reset the account/MFA for me).
Btw, I realized there is AppleCare+ (insurance provided through Apple) for iPhone, and for that matter other Apple products too. It's not too expensive. There are other insurance offered by insurance companies too.

Also Mint Mobile has a plan for me :-) I think if one decides to buy, the Apple's plan probably is better.

I think I will probably pass on both for now: I am going to self insure my iPhone. In my past, I had two instances that I dropped iPhone into water or other liquids, and I was able to dry it out myself. For this episode (the XR screen break), it's my 13 year old's fault, and I still have to pay, the cost is about $200, because the phone in its working condition would be worth $200.
One thing to take note though, with the protection of iCloud, the iPhone thief cannot use the stolen iPhone directly (they could disassemble them and potentially use it for parts). Here is an example I am aware in which the victim likely got killed due to a robbery of iPhone (in year 2012).
"According to police, a man later identified as 18-year-old Keith Esters confessed to having targeted Megan after seeing her talking on her iPhone, for which she had replaced her Blackberry just a month earlier. In the process of the robbery, Esters shot her twice and killed her, police said."
