Responding to your request for recommendations here since they won’t be summer 2023 series. The heavy hitters would be Overlord or Re:Zero, but both have multiple seasons & are pretty well known. For something shorter & more obscure: The Far Away Paladin, Skeleton Knight in Another World & I’m Standing on a Million Lives. I’ve heard good things about Grimgar of Fantasy & Ash, but haven’t see it yet. If you’re willing to forgo the isekai requirement maybe Goblin Slayer or Alame Ga Kill. Hopefully you’ll find something that works for you.
