I'll set aside the obvious Domane and Roubaix, although both a great bikes. Also, I have a 2020 Defy Advanced Pro 0. It's a terrific bike and right around your budget. I think a new Defy is coming soon though. You might want to hold off.

Other endurance road to consider:
Cervelo Caledonia 5
Willier Cento 10 NDR
Cannondale Synapse HI-MOD
Canyon Endurace CF

Fast riding gravel race bikes to consider:
3T Exploro Racemax
Ridley Kanzo Fast
Open U.P.
Santa Cruz Stigmata

Also, don't forget about cross bikes. They are racier than both of the above and can handle pretty much anything. I particularly like the new Giant TCX and the Specialized Crux.
