IMO the better long-term solution is to educate everyone on the concept of preparing and structuring a meeting adequately in advance, to only invite the people who should really attend, and not be afraid to say no when you believe you don't need to attend when justified. IMO the person creating the meeting has that responsibility to prepare and structure the event to minimize the time required. I personally include a document in the meeting invite containing the talking points in advance, which gives the time to those who participate to prepare their content and add more points if relevant. I guide the discussion through those points while also taking notes, and when the meeting is over I share a meeting summary to all those who attended so that we all have that info written down, easy to Ctrl+F if needed. So far I think everyone enjoys the effort I put in these. The rest of the work is documented through our incident management system to keep everyone in the loop, and wr have our group chat for the ad-hoc discussions.
