Midgard comes around with some nice ideas and definitely hits the High Fantasy track of DnD 5e. Dark Fantasy is correct depending on your own assessment, as the Dark aspect sometimes shines through stronger and weaker. It is definitely a world of conflict and possible adventure. What would have helped Midgard a bit more would have been a clearer identity, which distinguishes itself a bit more from the generic setting and its many references to existing competing products and real world examples.
