Hi there! There are a TON of resources out there. As a start, we've collated a bunch of training resources on a variety of ed tech products (including Google Workspace for Education ones) on our district ed tech website, which you can check out here
. I would encourage you to take note of the authors of many of these resources, including ShakeUp Learning (Kasey Bell), Ditch That Textbook (Matt Miller), Control Alt Archive (Eric Curts), and more. Those are the people I would encourage you to follow on Twitter and to subscribe to newsletters via their websites.
