hmm maybe I missed some suggestions but why not:
Clannad:
2 seasons a 23/24 episodes each with a better 2nd season and don't watch the movie (maybe after you finished).
Dramatic anime with cute characters. Might not be a shoujo, but it feels like one xD
Ga-Rei Zero:
1 season with 12 episodes. Less of a shoujo anime but the POV is from a female perspective (don't really remember
the definition, but it's an action anime focusing on fighting but also on the relationship between the characters)
True Tears:
13 episodes 1 season, but might not fit what you are searching for. It's a serious drama, with main focus on the
romance and love triangle at hand.
K-On:
2 seasons with 13 and 26 episodes. It's a cute anime with nice soundtrack and it's kind of a slice of life showcasing
cute female characters in the light music club forming a band.
White Album 2:
12 episodes, this season, not finished yet, but today or tomorrow the last one will be released. Again about music
but this time focusing on the drama and romantic relationship between the 3 main characters.
Durarara!:
24 episodes with a weird plot that at first is very confusing, but later when everything is revealed it makes a lot of
sense. Involves fighting scenes.
Dantalian no Shoka:
12 episodes, about a story involving books, a bit of magic and a semi jealous female main character.
Bokura Ga Ita:
24-26 (can't remember) episodes. Might fall into the category: not good enough animation/graphics, but I think you
might like it as it is a shoujo fully committed to romance and as far as I remember there was no real triangle in there.
Toradora:
24-26 episodes full of comedy slice of life and romance.
Here comes a list with popular comedy shoujo anime, that you probably know already:
Kaichou wa Maid-sama
Special A
Ouran high school host club
Vampire Knight 1 & 2
Sorry if they don't suit your tastes. As you can see I mostly watch anime which involve romance. So that's why I
recommend mostly romance anime. Hope you find something useful from the list.
EDIT: You really shouldn't skip out on Code Geass. You could leave out the mecha and instead add magical armor
or tamed beasts or something else that can be abused for war and it would still make sense (most parts of the plots),
because what's important is not the means but the result! Character development, twisted plot and unpredictable
events, make this anime so good.
