Hi - the bike depends upon the type of riding you want to do and what you want out of riding.
Do you want comfort? Durability? Speed? More upright riding position?

Definitely want to look at bikes with larger tires as they would be more comfortable.
The CycleCross type bikes are fast but have a bit larger tires for more durability and comfort than a skinny tire road bike. Check out the OmniStrada which have knobbier and larger tires than the regular cross bikes. They also have top tech tubeless compatible rims which you can easily convert with sealant and kit to being virtually flat free :) Check them out:
