If you like Cowboy bebop, you will also enjoy Samurai Champloo (same director).

My fav anime is not a serialised one, it's Perfect Blue by Satoshi Kon (RIP). It's extremely cinematic, some big movies like Black Swan and Requiem for a Dream copied its framing quite a bit.

Otherwise a serialised anime I really liked Mushishi, very interesting world building and great concept. I also love Steins gate, Kaguya Sama and Bakemonogatari.

As for manga, I love Goodnight Punpun, Aku no Hana, and Chainsawman. They just offer something no other media can copy. Goodnight Punpun and Aku no hana really changed my perspective in life for a long time.
