This is based on your list and are longer (50+ epis) action animes that haven't been recommended yet.

Vouch

One piece. We like the same genre. U will love it

So I've seen every anime on your list and ill have to agree with the above posters here.

One piece and FMA brotherhood. Tbh if I were you I would start with FMA first since one piece is such a big investment.
