The first thing you need to do is review your CC&Rs or ask the President of the HOA what the procedure is for getting policy review. You are right, it makes no sense that a bottom floor have any regulation for flooring, but these documents are often drawn up as boilerplate and don't always make sense.
Once you figure out how to get a review, come armed with as much info as you can. Unfortunately this is one of the drawbacks of living in a condo - you have to ask permission.

As Russ has mentioned, personal taste/lifestyle do need to be factored in. Personally, I've done a fair amount of research and am going with a Trex type of material. It really has improved over the years and I know that I'l appreciate the low/no maintenance of Trex.
I've had a redwood deck and found it to be too much work!
