Of those anime mentioned in the poll, I have only seen Midori Days, but enjoyed it. I also loved Ika Musume. Based on the OP's preference for slice of life with weird elements, try Seto no Hanayome (My Bride is a Mermaid) or Kyaoran Kazoku Nikki.
Also, gonna have to also give a special shoutout to Clannad and Clannad: After Story. Everyone, go watch them. Starts kinda slow, but ALL THE FEELS! I personally didn't enjoy the ending of After Story (too deus ex machina), but everything up to that point is exquisite. Hmm, have to go watch it again...
You may also enjoy:
Yakitate! Japan, K-ON!, Bakemonogatari, Eden of the East, I My Me! Strawberry Eggs, and Tiger and Bunny.
Good luck finding something fun to watch!
