We considered factors including: large attendee count, live feedback, several speakers/presenters who can share their screen, and allowing others to draw on that screen or edit the document. There are many more options such as Talky, etc. These web conferencing methods work for Linux / macOS / Windows / Android / iOS.
High quality livestreaming HD broadcasts via an API requires just a bit of reasonable technical knowledge to accomplish. Google Meet only requires a web browser and plugin (or mobile app)–it’s simpler to get started and is a good business-grade choice.

Zoom currently allows limited free use. Paid plans have unlimited time with a large participant count. The Zoom client is available for many platforms, or can be used directly from the web browser. The Zoom Linux client also works well.
GoToMeeting allows small free meetings, with a large participant count on paid plans. HTML5 GoToMeeting works well in the Google Chrome browser across operating systems.

Discord can be used from an HTML5 browser, and allows thousands of simultaneous many-to-many voice and text chat users. Several speakers can share video/screen and audio as well. Discord is free to use with very low latency HD voice. Discord uses discontinous voice via voice activation or push-to-talk. Many-to-many conversations allows interrupting without pause/break.
