I brought up this issue to the WikiProject Anime and manga on Wikipedia, as they work with many more mangas and animes and face this problem every day. One of the admins told me this:

Our convention for AoT media is to use with the following priority:
 * 1) Kodansha USA manga spellings (Eren Yeager, Wall Sheena) – Most AoT-related articles, especially manga, the guidebook, and our character list.
 * 2) Funimation anime spellings (Eren Jaeger, Wall Sina) – Apply only to the anime-specific articles: List of episodes, Home media / DVD articles, and filmographies like Bryce Papenbrook
 * 3) Other acceptable English manga and anime spellings from official sources – includes anime and manga captions from early translations like Crunchyroll/Hulu.
 * 4) Japanese romanized spellings – what you see on pictures for the Japanese manga and anime. With macrons and all. – usually this is only if we can't find any official English spelling from 1-3. This is where you might see "Sīna".
 * 5) Fansubs (low-to-no priority). They are not reliable sources for Wikipedia.

Note that we also alias all the spelling variants to the appropriate articles and use Nihongo a lot. We've done this for other shows too: One Piece (which has a ton of spelling variants and even name variants), Case Closed (lots of variants in names across manga and anime) and Fairy Tail (spelling variants between manga and anime).

For your Wikia, you can pick whatever scheme you like. Some wikias like using Japanese romanizations and names for just about everything, so you'd see a lot of Shingeki no Kyojin instead of Attack on Titan, but we're mainly English Wikipedia so we try to use titles as released in the English like Attack on Titan: Before the Fall as much of the media has been officially translated. We picked the manga first because it was printed extensively in manga and that's also the original source material. Similarly they'd like to use Detective Conan instead of Case Closed; that's been a debate for a while.

I'd also suggest NOT creating separate articles for Eren Yeager and Eren Jaeger. This isn't Robotech or Cardcaptor Sakura/Cardcaptors. The differences between Japanese and English translations or manga and anime aren't so radically different to warrant that. Also look at the extensive talk discussions on the spelling for the names.
