Hi Jeff,
Welcome to Bike Forums.
No such thing as a comfort bike.
"Comfort bikes" place all of your weight on the butt. That is not comfort.
Front suspension works on mountain bikes where one rides over rocks and tree roots.
I started road riding at 65 on a used $15 road bike.
Road bikes allow one to distribute your weight between , Legs, Hands, and butt.
Test ride them all before you decide. Have fun searching.

You might try Craigslist in your area for a used one.
