Calendar Options

Hello - we have just launched a new SP intranet at my organization... one question we're struggling to find a solution for is displaying an existing shared M365 calendar on this intranet.  From what I've read, the only calendar options that exist are 1) linking an existing Microsoft Teams calendar; 2) enabling the M365 shared calendar to have a public HTML URL and linking it from that page; or 3) use some power bi/app to sync the events based add/update/delete.  I've had mixed results with #3, and #2 is not preferred as some non-public events could be posted on this calendar.

Any other options anybody can think of?
