Looking through the shows I have enjoyed the most in the past couple years here are some that I don't see on your list:
- Bocchi the Rock
- Eminence in Shadow
- Lycoris Recoil
- Heavenly Delusion
- Oshi no Ko
Also, it might be (quite) a bit older, but if you really feel like you need something dripping with melancholy, I would recommend Mushi-shi.
