You can pretty much completely ignore the different race's initial stats because when you hit 50 they really won't make a different at all. Even before 50 they don't have much of an impact. For what class I'd start with I'd say it doesn't really matter just pick whatever class sounds the most fun to you. Although if you level arcanist at level 30 it actually branches into one dps job and one healer job so it's always nice to level two at once I suppose. If I had to pick a class that's easy to get into and nice for starting off I'd probably pick archer because it has nice mobility, decent dps, and can support with songs once it becomes a bard, and it also has very nice aoe abilities.
