Learning basic Zoom Meetings adminstration concepts and skills

Hello. I am brand new to Zoom, although I did retire from a ~40-year IT career, so I am hopefully not completely ignorant of many of the concepts. My high school class is planning a reunion during 2027, and we would like to make it a hybrid live and remote participation event to accommodate some of our classmates who are no longer able to travel long distances. I viewed the introductory user videos on the Zoom learning portal, and I hoped to follow that with educational material on the basic concepts and skills for Zoom Meetings administration. I did find some course ware on that subject listed in the Zoom site, but it appears that it was all retired in March, 2026. I don’t see anything listed to replace it. Also, some of the user introduction guides were not as detailed as I had hoped. For example, I could not access a screenshot of the participants that showed the sidebar with their names. Examples of that, and similar screenshots, would be most helpful. What would be the best way for me to find more information of this kind? Just FWIW, our budget is quite limited. While I do intend to sign up for a paid subscription at least two months in advance of the event (most likely to be held in early September, 2027) so that I can begin planning and testing, I really need to gain most of this knowledge before doing that. Thank you.
