The Paperbag Princess still just makes this age range.
I loved the Ramona books from about 7.
I also loved "The Practical Princess and other Liberating Fairy Tales" but it's out of print now. You can get second hand copies though and they're worth it if you have someone into princess stories/fairy tales.

Some favourite movies I remember were
Mary Poppins- the submission of the wife is the one grey area in this movie but I did learn what the suffragette was movement from her!
Annie
The Parent Trap- the old original one, not sure what the remake is like but the girls were very savvy in the first one
