Arguably, it might help marginally if you're healing someone outside of your own party where the targeting mechanics are a little more complicated (I find mouse clicking works best for this, personally). This is probably a less common occurrance anyway, but I thought it might be one worth mentioning. In almost every game I've played it's been as a healer as well. But you should definitely choose the race/type/height/whatever you like best rather than for any sort of advantage.
