My company also uses MS auth + 2fa for everything. Even signing into corporate G-suite :-). But I do not like the Microsoft Authenticator - I previously had issues where it would not show the number - and I was able to switch to a different TOTP provider. It’s a bit buried in the menus but possible

Unless they have explicitly disabled it even m365 has the option to add a totp 2fa method. Might be worth double checking.
