Seems that everyone else has said the same as what I mostly already do, but I’ll just make a couple comments on the student communication topic:
My university already created a Microsoft 365 account for my university user, which included Teams. For my threat profile, I don’t consider Teams a terrible option if I’m only using it for study purposes, so I’ve communicated over that for assignments before (web UI only).
Otherwise like others have suggested, some students are open to something like Signal (a fellow student got me onto it years ago) if you kindly ask and mention upfront that it just requires a phone number. I did an assignment over Signal with two other students, so it’s very doable.
