Tokyo Godfathers is an amazing and deeply human christmas comedy about homeless people in the Tokyo streets, filled with magical moments of cinematography.
Paprika is a less lighthearted story about inner lives, dreams and ambitions set across a sci fi backdrop where people are learning to enter each other's dreams and link them together. It has gorgeous dreamscapes and an amazing soundtrack as well as a fascinating plot and interesting characters.
Thre's also Makoto Shinkai's movies, which have good cinematography and interesting themes and soundtrack, as well as somewhat interesting characters (though a bit samey). Your Name is excellent, with Weathering with You and Suzume being good but not great. 5 Centimeters per second is nice as well. Children who chase lost voices underground is his most Ghibli movie and I'd say it definitely gets the tone and aesthetics right for the Nausica/Mononoke era of Ghibli.
On the Ghibli side, I quite enjoyed Studio Ponoc's Modest Heroes, which was a collection of shorts by Studio Ponoc (which has some Ghibli Veterans in it as well as younger talent I believe). Kanini and Kanino has the adventure elements and aesthetics, Life ain't gonna lose has the small child PoV element, Invisible has the social elements.
