This is a great question. I'm struggling myself jumping from 30 minute meeting to meeting for 6 hours in a day and I have to remember what is said in each when I haven't internalized all of the things (so my shorthand notes are often incomplete or even unintelligible) and all the tasks and who they are assigned to so I can follow up or pass them along. And At the sane time I have to multitask during meetings to actually get my job done which means I'm often tuned out for part of the congestion. And the whole time I have to respond to messages, some of them urgent issues that need quick action.
I do my best to capture everything in Obsidian, but the more stuff I have the harder it is to organize: does something belong in my daily notes, which is more accessible but hardest to find, or is it a quick task where once I complete it and delete it I've lost what was done, or is it a standalone task, or is it something that should be documented in project status? FUUUUUUUCK!
I spend 30-60 minutes a day just organizing my notes and tasks. I have to do any actual work (including said organization) before 9-10am because that's when the deluge of meetings start and once they are done for the day I'm just spent.
