The new Specialized Crux would fit the bill nicely. Its an endurance road bike that fits wide tires. Basically an Aethos with larger tires. I'm guessing anything with the "S" is out of your price range.
What tire size is your primary, and what is the range you would like to accomodate?
Personally, the Crux is pretty similar to the Canyon I bought actually (Inflite). Its my do everything bike (from road racing to gravel racing, commuting, single track (non technical)).
I don't know canyon's latest availability, but there are 3 choices - somewhat separated by tire size and geometry (race to endurance)
Sporty/racy and super fast: Inflite
All around gravel: Grail
Endurance, touring, fatter tires: Grizzl.
