I want to do an online event (ideally in zoom) that has split-screen interviews *and* breakouts

In the non-virtual world, I’m involved in a lot of events where there are two to four people talking on stage, followed by interaction with the audience, and between audience members (eg: we ask people to talk to the people sitting near them about what they just heard).
I wonder if there’s an online tool that can replicate this.

Zoom is frustratingly close. But from what I understand, there are two separate products, "meetings"and "webinars" which each do part of what I want but not all of it.

My understanding is:

Zoom “meetings” allow breakout groups (for stuff like talking to the people at your table). But as near as I can tell, they don’t let you highlight a small group of people (you can spotlight one person, but not a group) and users control how they see things.

Zoom “webinars”, I think, give more control over how the “on-stage” part appears, including being able to present a “panel”. But they don’t let you have breakout groups.

I’m hoping for some way to bridge this divide, using Zoom or other tools: To do an event where there’s an “onstage” part, with a small number of people talking, but which also allows the audience members to go into video breakouts to talk to each other.

A couple of possibilities that have come up as I look into this:

1) Use two tools. Like, do the "panel" part in facebook live or some other streaming platform, and to the "discussion" part in a Zoom meeting, and have users switch between the two. This seems potentially clunky.

2) Do the interview using a tool apart from zoom meetings that allows for split screens (a video tool like be.live or streamyard. Or even just a video chat). Then share that screen into a Zoom meeting. I'm not sure how technically feasible that is... I can't figure out how to make this work...
