Too many good shows to list, really. One thing I can recommend is watching some currently airing shows if you aren’t already. Sounds like you watched Darling in the FranXX, but that was popular enough that maybe you just heard of it by chance. You can view per-season shows on livechart. It can be fun to watch one or two dozen shows that sound interesting as they air. You end up finding a lot of interesting stuff, because only having to watch one episode a week means if you stay caught up you can manage to watch a lot more total shows at once than you probably would watching already finished shows. Sometimes a show looks only a bit interesting, and you give it a shot just because it’s airing. I’ve found a lot of shows I’ve enjoyed this way, so I find watching airing stuff to be more rewarding than just looking at what people happen to recommend.
Hakumei to Mikochi was a show I watched when it aired a season or two ago, and it was amazing. I can’t say I would’ve watched it if I’d just found it on its own, but I tend to watch a lot of airing shows at a time.
