Exchange Online Kiosk and basic authentication

We have part of users using "The Exchange Online Kiosk" License and they all are using Microsoft Outlook 2013 / 2016 Email program with POP protocol. Just to save cost for subscribe fee. And this Kiosk license will be expired next year 2023.
Q1. Microsoft will begin disabling Basic authentication after October 1, 2022, can we turn back on Basic authentication after disabled? Then we may upgrade Exchange Online Kiosk to Online Plan 1 license for these users and change to use exchange protocol instead on POP protocol next year.
Q2. POP uses couldn’t access email server last month (July-2022). And didn’t know what happen that time. So just turn off modern authentication that time. After a period, pop user can access Email server again. But make all exchange user to re-enter password once.
See that Org Settings > Modern authentication. Can allow basic authentication after turn on Modern authentication? Won't affect POP connection?
Q3. Though knowing that POP user can configure to use MS Graphic API or Thunderbird which supports OAuth2 authentication, it’s too complex. Is it better to upgrade Exchange Online Kiosk to Exchange online plan 1 and use exchange protocol ASAP? Seems not much users to use Online Kiosk license.
Q4. If use exchange protocol with Modern authentication turning on, don't need to force to use MFA again. Right?
Thank you.

Refer to the FAQ here: Basic Authentication and Exchange Online – September 2021 Update
How can I get a longer exception? I still want to use Basic Auth after October 2022
We are not providing the ability to use Basic Auth after October 2022. You should ensure your dependency on Basic Auth in Exchange Online has been removed by that time. Basic authentication (outside of SMTP) will be turned off for everyone in October 2022, including tenants who have previously opted out using our self-service tool.
The link here introduces about the differences between The Exchange Online Kiosk License and Exchange Online Plan 1, Plan 2. You could consider upgrading it to get better experience.
And yes, If use exchange protocol with Modern authentication turning on, don't need to force to use MFA again.
