The only thing I take issue with is the constraint of Netflix and Crunchyroll. if you use Netflix for strictly anime I would just recommend you quit that and just grab Hulu since their back catalogue on anime is just legendary, but if not oh well.

Mob Psycho 100, same creator at One Punch Man. The MC is a nearly all powerful telekinetic who desperately wants to be normal to the point of suppressing his emotions. I personally like if better than OPM.
Drifters, created by Kouta Hirano (Hellsing), At the moment of death Historical figures from throughout time are whisked away by someone to a world. Toyohisa Shimazu wakes up to encounter Oda Nobunaga and Yoichi Suketaka Nasu who decide to free some elves from the tyrannical human government.
Choo Choo, all aboard the feels train! Your Lie in April, Kousie a piano prodigy can't play after his mother's death but things turn around when he meets Kaori, a violinist, slowly things start to move forward again.
a great complimentary series to that would be,
Ore Monogatari, Takeo looks like a fucking gorilla and his best friend Sunakawa looks like a playboy so poor Takeo never has a chance since girls always fall for his best friend but when Yamato appears he goes for it anyway.
This series is so damn sweet and innocent it is a very funny and uplifting counter to Your Lie in April.
