Hi Richard, you can look here:
https://experienceleague.adobe.com/docs/workfront-learn/tutorials-workfront/fusion/welcome-to-workfr...
The above link is the first in a collection of pages that offer Fusion training. The videos are distributed across a collection of nested pages/sections. You can see those sections on the left sidebar. I'm not aware of a single zip file or something similar that allows users to download the full collection at once.
