Like Lisati said, we're all people. But thank God we're not all cookie cutter people. I'm glad for the differences. If someone starts calling people "breeds", that's a different story.

The terms "race" and "species" belong to different scientific disciplines. "Species" is a term in biology, whereas "race" is a term in anthropology. Context needs to dictate the correct terminology.
Who you gonna offend? E.T.?
Both, species for the types as a whole and race as distinct or identifiable group within the species based on similar biological criteria based on social perceptions and constructs. I don't really see why you should omit the terms and concepts since in an intergalactic world there would most certainly be species out there like ourselves that embrace such concepts. In the vastness of space there is indeed no limit to the vastness of stupidity and misunderstanding that would certainly make some some interesting epic drama.
I don't see any species of any number or intelligence to be completely homogeneous in their culture, attitudes, and opinions and thus race is still something that is sadly still significant just as is creed, ethnicity, class, etc. Just an observation one should note if they truly want to their fictional world to have some depth of reality to it.
In biology, races are distinct populations within the same species and does not apply to genetic differences but phenotype.
Yes, it is heavily (negatively) connotated, but race is actually a scientific concept (without ascribing inherent value or non-value).
If you are writing a sci-fi novel, maybe the whole discourse about race has evolved to a more transcendental point - so that the word could be used again
