The deity you picked used to have a small effect on elemental resistances before those damage types were removed from game play (think that was start of Stormblood?).

For some players who are heavily into role play, the choice still has meaning.

Also regarding the Encyclopedia Eorzeas, they're written to be in the style of Eorzean scholars who may not have the correct facts (leaves room for SE to retcon parts of lore if they feel the need). It's probably better to not lean on the information in them too heavily.
