I settled on the Trek FX 3 Disc based on all of the online reviews saying that the regular FX 3 does not stop very well. I figured that the small additional weight will not be noticeable to me as a beginner and I am not planning on climbing big hills or going 100 miles at a time. I get it next week and am very excited.
Thank you all for your input. I am sure that I will have more questions once I start riding.
