every movie from Studio Ghibli, while secular, is family friendly and has good moral lessons & protagonists with strong ethics.
they are anime, hand drawn - the artwork and stories are of such quality that adults can enjoy them, & being cartoons, kids may enjoy them & the plots are easy enough to follow for the young ones too.
there is no "crude" or "vulgar" humour or innuendo like you find in Shrek (for example) or so many other popular American animated films, an the artwork & storytelling is far superior.
they are all quite fine IMO, a few of the best titles:
Spirited Away
Arriety
Ponyo
Tales From the Earthsea
Howl's Moving Castle
these are all the work of Hayao Miyazaki, i consider him our era's "Walt Disney" - by that i mean the good Disney, not the Disney of the last few decades.
many consider his finest movie "Princess Mononoke" -- this has a little darker tone but nothing i would worry about showing a child who can handle Snow White or the Wizard of Oz without nightmares. the most light-hearted of the list i gave would probably be Arriety & Ponyo
they are all quite good, highly recommend!
