Test ride as many as you can. In the Trek line the Domane frame has more stack and less reach than the Checkpoint. However the Checkpoint comes with shorter stem and reach bars. I have a ‘21 Domane SL6 and ‘23 Checkpoint SL5. The Checkpoint with the stem flipped up and no up high is surprisingly as comfortable as the Domane with same size frame.

There are others makes offering higher stack like Specialized Diverge and Salsa drop bar bike's.

But take your time and test ride.
