Eventually some meaningful competition from the likes of Don Bluth started to push them in the right direction (Secret of NIMH, Land before Time, All Dogs Go to Heaven, etc.) and not too long afterward they were doing things like Little Mermaid, Beauty and the Beast, Aladdin. Quite an improvement, though I dare say the storylines have never quite caught up. (Of course, all of Bluth's stuff would later be undermined as it was sequel-ized to Hell and back, like The Land Before Time XXIV: Teach Your Kids Roman Numerals Edition...)
Right now, though, after seeing Pixar's homages to Ghibli, I'm anticipating the impact of recent works like Puella Magi Madoka Magica, which really pushed some boundaries in Japan. (If you're not familiar with it, I'll just say... imagine if Pan's Labyrinth had been actively marketed to little children as a happy family film and an homage to Alice in Wonderland... and then translate that willful deception and the profound darkness onto Sailor Moon.) If it does make a splash in the youth entertainment industry at large, that will be quite interesting indeed.
The second list of films you mention have emotionally moving plots and I'd consider them a good fit for the next demographic bump, roughly 9-13. I think I might have cried to a film for the first time watching ADgtH as a kid.
Puella Magi Madoka Magica is definitely mature. It has intense situations, highly emotional plot, and story elements that younger humans would be less equipped to relate to. I still highly recommend watching at least the first 3 episodes. If you're still on the fence watch another 3 episodes. The third movie is new content... I couldn't resist it, but the series/first two movies are a complete story without it.
For example there is one where Donald is up against the aracuan bird, where he eventually is fed up and pulls a Maxim gun out of nowhere.
The bird survives unharmed, classic cartoon style, and Donald snaps, starts behaving like said bird, and wanders off as things fade to black.
Good luck finding that scene today. Now it just jumps from the bird sitting in a lawn chair to Donald wandering off.
