I liked Silent Voice a lot for that as well. The characters were grounded in reality instead of being melodramatic caricatures or trope types. It kept in a lot of humanity and introspection. People acted normal and for the most part mature or within the bounds one would expect for their age.
DDOS against a little self hosted instance isn’t really a concern I’d have. I’d be more concerned with the scraping of private information, ransomware, password compromises, things of that nature. If you keep your edge devices on the latest security patches and you are cognizant on what you are exposing and how, you’ll be fine.
