Argonians make great wallets.
...and Nord skin works the best.
Anyway, play whatever appeals to you. I play an Argonian that began as a sneaky archer, but later took an affinity for conjuration magic. Conjure Dremora Lord to tank, then conjure bound bow to offer ranged support. Works great for me.
I might suggest just playing without adding perks until you find what you like - then begin adding perks to those respective trees.
