Windows 10: Microsoft Authenticator - non MS accounts added as 'personal'

Hello,I've recently started using the Microsoft Authenticator app for my two work MS accounts. I also decided to add some personal accounts that are non-Microsoft to the app e.g. amazon, PayPal, non-MS mail etc by scanning QR codes from the website. All of them were added successfully and they all seem to work well with 2FA codes from the app. But I think I may have added some of them as 'add personal' accounts not 'other' in the app. And my point is: is that a big deal?Is choosing 'personal account' option applicable ONLY for MS accounts?

Windows Microsoft account authentication

I have a valid Microsoft account and a Windows 10 PC with Hello/PIN account login enabled. I also have the Microsoft Authenticator app installed on an iPhone and configured for the Microsoft account. Additionally, I have two step authentication configured
for the Microsoft account. With all of that said, I have become very exasperated while trying to unravel the various authentication paths (and their security implications) through this multi level login security scheme. I find the associated account security
documentation to be woefully inadequate. Thus, I would like to pose the following list of questions for starters.

1. Does Windows Hello/PIN amount to a two step verification login procedure for my Microsoft account?

2. Does approving a Microsoft Authenticator login attempt (without two step verification explicitly set up)

amount to a two step verification login procedure for my Microsoft account?

3. Does approving a Microsoft Authenticator login attempt (with two step verification explicitly set up)

amount to a two step verification login procedure for my Microsoft account?

4. If answers to both 2 and 3 are yes, then what does explicit set up of two step authentication do?

5. Does a coherent, comprehensive document explaining Microsoft account security configuration exist somewhere?

6. If the answer to 5 is yes, wherer is it?

Thanks in advance.
