Well, if we are talking about currently airing shows, Frieren is likely to supplant Oshi no Ko for AOTY for me so far. It is a very different kind of show, melancholy, slow, thoughtful, but it is an excellent adaptation of an excellent manga. Also I have been enjoying Eminence in Shadow, but that one, being season 2 and a parody of the isekai genre, is very hit or miss with people if they connect with the humor or not. I have heard good things about Shangri-La Frontier, so that one might scratch an action itch for you.

If we are opening up to not currently airing shows, Samurai Champloo is one of my favorites when it comes to creative sword fight choreography. Lycoris Recoil is excellent at gun fight action. If you are looking for feel-good SOL like spy family, you could try Buddy Daddies (though I haven't seen it) or Usagi Drop (the show is good, avoid the manga). Tengoku Daimakyo might scratch a mystery, adventure itch. It isn't explicitly a mystery, but there are lots of mysterious things going on.

Check out Sousou no Frieren.
