Legend of The Galactic Heroes. Either the OG or the remake (Die Neue These). Complex characters who hold totally different perspectives and philosophies trying to outthink each other in a giant galactic war.
Polar bear cafe was pretty good. Cat soup too, but that is only one short. Also I like the old ones like Devilman (1970s not reboot), Mazinger Z (ROCKETU PUNCH!), Galaxy Express 999, etc. The Batman Ninja thing (2018) was surprisingly good (and I'm sick of superheros!), man I know I have more but I'm blanking, I may come add more later.
