My advice would be to choose the race that fits what character concept excites you the most.
Do you want to play a nobility with a deep rooted history in Ishgard? Then Elezen would be the way to go.
Do you want to play a character with more of a foreigner background? Just how he gets or already got integrated into the Ishgard is entirely up to you.
Either race can be entrenched in Ishgard the culture, just in a very different way. I don't think you will miss out on any particular RP groups unless it is inherently tribal or nobility kind of RP.
