It's a bit dependent on what kind of world you're playing, but I usually look around a little bit before I settle my capital. I often found that moving just 1 or 2 tiles from your spawn location you may get an additional luxury or resource. Of course you could get any tiles just outside of reach from your capital with a second city, but at the start of a game I usually want to keep all options open, also the option to go for few but large cities,for which you need an optimal capital location.
