Welcome!
Thought I'd answer your query about the races, since you're interested in a bit of the game's lore of those particular three. The truth is, except for perhaps the elezen and au ra, it's difficult to lore break this game's races. The hyur are humans, and so can be anywhere, do anything, just like any other fantasy setting. Unless you're talking about highlanders, at which point you're pretty much looking at a Scot and/or Scandinavian person. And really, the rest of the races aren't so different. The miqo'te are by far the most popular and populous race. Really, cat people everywhere. Just do a Google image search of miqo'te memes. But, like hyur, they're hard to lore break. They all came to Eorzea on boats a long long time ago, before the rain and before the snow, and were tribal until they weren't. Now the entire race is composed of rebels out to prove that tribalism is bad. Except for the ones who are still tribal. So, like I said, can't go wrong. Then you have your elezen, which are a bit more lore heavy because of Gridania, Ishgard, and duskwights. Basically, your elezen is going to be of one of those three categories, and it's going to heavily effect the concept: tree-hugger, medieval fanatic, or sour puss. Roegadyn are about as easy as hyur, because even though the game sort of kind of maybe thinks about hinting at roegadyn lore, it never quite broaches the topic. Roegadyn come from mountains or islands, except for those that don't, and name themselves either after thematic names earned by deeds, or keep their racial names, except those who don't. Pretty flexible. Finally, you have the weeble wobbles - I mean the lalafel! Again, these guys are about as lax as hyur, with the exception that they may or may not compose the majority of the aristocracy of Ul'dah. Finally, au ra. These guys actually have some distinct lore. They're from Doma, they're tribal, they have some absurd naming conventions that adhere to Fuedal Japan's old culture, and they didn't exist on Eorzea before about 8-9 months ago. Oh, and they're not dragon people, they just look like it, and their horns can "hear" since they don't have ears.
Obviously a lot of players take their own approaches, making adjustments here or there to suit their styles. There really isn't any lore breaking that you need to worry about. Just present it well, be familiar with the norm, even if you don't represent it, and have fun.
tl;dr: The races in ease of lore content, from hardest to simplest: Elezen/Au ra, Highlander, Lalafel/Roegadyn, Miqo'te, Midlander.
