I like how Work To Game discuss different community topics and don't just repeat whatever is posted on the Lodestone. It's something to listen to at work. Tea time with Meoni is a similar but less scripted format of two people talking about the game.

Mr. Happy covers interviews which I'm too lazy to keep track of otherwise. Sometimes I listen to his patch note reading or live letter digest if I haven't had time to read them.

Zepla HQ has fun videos and also some commentary on community topics.

For guides I just use the search function. Many content creators make guides about different things and I don't have a favorite.
