Mechanically the Raven Queen is the favourite for most, because of Hexblade, or undying for defensive necromancy spells, but I always had a penchant for the archfey patrons, for Roleplay purposes, like Hyrgam the Prince of fools or Oberon and Titania.
You usually get some weird and strangely requests for them that seem like jokes most of the time, and your interactions in the campaigns use to be really fun. I remember when I played a deaf warlock that received coded messages from his patron in notes he found inside roast chicken or in a spiked rose in his bedroll. Fun times.
PD: I concur that, if they allow patron interactions ingame, they are going to be tied to the warlock´s archetypes, I think. I hope I´m wrong because the warlocks have plenty of potential, and I´m still sore about the warlocks depiction in NWN games.
