junO- didn't really give you a good answer..
This should help a little bit:

Basically to get 1080p resolution for your group meetings, what you need is at least Business licenses (I don't count Pro with Events or Webinars Plus as a valid option). Typical Pro license is limited to 720p.
Previously there was a limit on initial order for Business licenses of minimum 10+ licenses.
But now that limit seems to be removed (although I may be wrong here).

On more small point to add here, @Srcsds1.
As this screen shot from Enabling HD video for Zoom Meetings shows:

Just because you have Full HD enabled doesn’t guarantee 1080 streaming. Several other factors come into play. Before you make a Zoom purchase decision, I’d recommend reviewing your hardware and setup details.
