It seems that contact points are important, and drive train matters, albeit less than outside on the road. Apparently frames are not as crucial, although there is a difference of opinion.
I have ridden two rather different bikes on my trainer over hundreds of hours in total. Both are set up very nearly the same in terms of fit, almost identical. They do feel different after an hour, and VERY different after 2 hours. One is a climber, the other is an endurance bike. Both are carbon, for what it’s worth. I hope you find a great solution in your quest. Ride on!
