How to create a shared calendar view with filters & branching

I'm trying to create a Communications & Marketing calendar where each team (internal comms, external comms, marketing, digital etc) uploads their events and then they can all be viewed/or not as required.

Ideally the full list of fields would change depending on the team chosen in an earlier filed. For example, for the internal comms team it would have a channel column, for PR it would have a spokesperson column, for events it would have a location column etc. 

I've attempted doing an MS List calendar view and it's not bad but it uses time and date, when I only need date, and it shows everybody all fields. When I use 'filters' I can filter by some fields but not others and I don't understand why.

Is Lists the best tool to use? Can I do 'branching' in Lists like you would in Forms. It needs to be easy to view the calendar and to input new events because otherwise people won't use it. I don't mind investing some time to get it right up front.

Teams calendar doesn't seem useful at all. I don't want all this stuff showing on my personal calendar.
