Imperials would be nice thieves due to Luck of the Emperor (random bonuses to found gold) since it's not only on chests, but people, corpses, random drops, etc...

However, from a roleplaying standpoint, Argonians fit very well, as thieves usually need to run instead of fight, and the waterways of Skyrim make a very effective GTFO feature for Argonians...
