The Git Workflows Warehouse site has been extended to give characterisations of 5 common but contrasting workflows in our workflow definition framework. The workflows are Git Flow, GitHub Flow, Feature branches, Trunk-based development and Cactus Flow. Check the catalogue for links to their descriptions.
We also have pairwise comparisons between each of these workflows, using our framework, so you can get an overview of what they have in common and where they differ.
