Here is some more great classic Anime suggestions for you to explore:

Nausicaä from the valley of the wind
Spirited Away
Howl's Moving Castle
Cowboy Bebop
Neon Genesis Evangelion
My Neighbor Totoro
Ghost in the Shell

The best thing i think anime have is how wide the themes are, and how weird stories can turn to be a deep philosophical discussion.

From the examples above:

Ghost in the shell question what is to be human through the eyes of an android
Evangelion questions why we need other people to live

Some are just cool and fun (with some deepness, like Cowboy Bebop)

There is a lot of gems around among the thousands of shitty cringy anime that exist.
