I ride a Santa Cruz Stigmata roughly 90% road and the rest dirt (single track, fire road, "gravel", etc.). I love the ability to add and mix my routes up with the trails we have available here in the California Bay Area. I've done 80 mile full road rides and I've done mixed rides where I've hit multiple open space preserves.
I did mountain biking exclusively for over 25 years and wanted a road bike that I could still trail ride on and my bike is perfect for that. I never feel held back on the road and I suspect that would be the case for you as well if you chose the Diverge.
Tires and your gearing will make a difference. I have a 2x GRX drivetrain and I'm riding the 38mm Specialized Pathfinder Pro tires (tubeless) - they have a solid center ride so in a straight line its like a slick but in the dirt there are knobs for traction on the sides.
