I feel like the devs mostly hang out in Twitter and some Discords, and the content is mostly in Youtube or Twitch.
As someone else said I suggest goncy (that's his handle on Twitter), midudev and Brais Moure, those last two are Spanish and the first one is Argentinian, beware of the accents if you are just getting started.
They also have Spanish-only playlists
