I'll just recommend some more of the classics:

• Mob Psycho 100 (a boy with incredible psychic powers tries to learn to control his skills while growing as a person. 3 Seasons, complete.)
• One Punch Man (a man became a superhero "for fun" only for him to grow so powerful that nothing is a threat anymore. 2 Seasons, with a third on the way; S1 ends on a satisfying note, S2 is just setting up for a long-running arc)
• Madoka Magicka (the "dark" magical girl show. 1 Season, which is complete on its own, but there's also a movie (technically there are three but the first two are recaps) with a sequel on the way eventually.)
• Redline (a group of wacky racers participate in the most extreme race in the galaxy on a planet ruled by a police state that does not want them illegally racing on it. 1 Movie.)
• Kaguya-sama: Love is War (two high schoolers with crushes on each other refuse to admit their feelings, instead coming up with elaborate ploys to trick the other into confessing their love; it's definitely not because they're just shy teenagers, no, it's because all relationships are zero sum and the first person to say they care is the loser. 3 Seasons + a movie which takes place after the end of S3, incomplete)
• Monthly Girls' Nozaki-kun (through various means, a zany group of classmates all end up working as assistants for their classmate, ace king and secret professional shoujo mangaka Nozaki-kun. Features some Gender Stuff, including a couple I've seen described as "straight in the gayest way possible". 1 Season, incomplete, came out in 2014 so the odds of it continuing are very low.)

Also, though I haven't seen it, given you seem to enjoy most things by Studio Trigger I'll throw out Dungeon Meshi (aka Delicious in Dungeon) as well.
