A touring bike is a road bike. It just has geometry that handles heavy loads well.
They work peachy dandy for riding without loads, too!
And "road bikes" that have braze-ons handle loads and can be used for touring!
(confused yet?)
Basically, buy the bike you fall in love with and that loves you back. Don't worry about designations and categories; what matters is that the bike feels like it was made for you, and riding it is joyful to your soul.
I feel that love for my Surly Cross Check, which is a cyclocross bike that I use for fast road rides, dirt and gravel rides, grocery shopping, commuting, and plan to tour on.
Don't worry about what the bike is called. Just look for that "ahhhh, MINE" moment.
