Please suggest the most well written anime in your opinion!

Hello! I'm relatively new to anime and have only watched a handful of them and had a pretty bad experience with them. I feel like my main issue is the writing. There's just so much excessive fanservice, lolis, incest, blatant nationalism, redundant dialogue/exposition, the constant exclamation of the characters (not a writing issue, just something I find super annoying), working on a principle of telling instead of showing, etc. And I think I'd personally enjoy some anime that are known for having great writing. I'd consider good writing to be concise, show don't tell, compelling characters, and deep symbolism and themes (these aren't necessarily required considering there are plenty of stories with amazing writing that don't really have much of a theme or message, but it's nice to have one if there is). I'm open to any and all genres and am open-minded to almost anything, just no fanservice, please. Thank you!
