Another thing on that list that is easy to pass over is gitlab. The community edition is slowly but steadily adding more project management features, one of which is the "issue boards" - a kanban style issue view [0].

I feel like people may overlook gitlab when evaluating this sort of product because they think of it as "just" a git hosting solution, or because they assume that PM type features might all be paywalled. I'm sure real power users will find it lacking, but for simple workflows it does the job very well, and it ticks so many boxes in one solution.
