You can stain with an oil based stain and then apply a waterborne polyurethane. This will give you the look you're after with much less VOC (volatile organic content) load, although most floor stains have a high VOC content by themselves. I have stained heart pine with Bona DriFast stain and then topcoated with Bona Traffic Satin and have gotten very attractive results.

You can consider the Waterlox system, although if odor is your prime concern, then research thre pros and cons of using that. Hard wax oil, of which I have no experience using, may be another option for you.
