Totally agree with 79pmooney. If you really are new to road bikes, you don't have enough experience to make an informed decision. Way better to spend less on something less and ride it for a season or two. You'll be way smarter about what you want, how to tell if a bike fits, etc.
I bought my first bike used and rode it for 3 years before I bought a new bike in late 2019. Even though I was not unhappy with my old bike and put a lot of miles on it, I realized how ill-fitting it was for me once I got the new bike and had a fitting from the shop.
Good luck with your search.
