Yeah, I would hesitate to call this "normal," too. It could be that she's just matching expectations.
Anyway, what does age-appropriate topic selection look like? Kids will be writing on some of the same topics for years... What I Did Over Summer Vacation, What I Did For Christmas, When I Grow Up, etc.
I also wouldn't read too much into handwriting ability. Writing neatly requires a lot more time than writing quickly, and it sounds like she favors speed over appearance.
I was like this, too. Writing neatly was paaaaaaaainful, because it was such a slow process. Fast brains want to go fast.
