In TitanFall 2, I've unlocked one or two extra "factions" in multiplayer. They are each led by various characters from the campaign, but other than a lore description of what each faction represents, I can't really figure out what the point is.
What do you gain by joining a particular faction?

Some players said that leveling up factions unlock unique items for your emblem. They also point out that you'll have different voice announcers in the game. A second thread said the same things.
This site states:
These rewards are banners and patches for your emblem. Besides that, it doesn't seem like there is much more to factions. In the first link I've included someone also stated that you're more likely to be teamed up with people in the same faction.
