Any race will do for any class. Choose based on your own asthetic preference, for example, "I think wood Elf Rangers are cliche", or "I think Human Rangers are the coolest looking".
You will not lose anything nor will you gain anything by picking one race instead of another for any class.
As a "real world" example - I made a ratonga scout solely so that I betray with him and make him a swashbuckler... the ONLY reason I did it is because I think the idea of a rat-swashy is just too cool to pass up!
Oh, btw - there are no bad aligned rangers, so you didn't need to indicate that you wanted to make a good aligned one!
