I have the G-One all-arounds in 38mm on my gravel bike, and I'm running tubeless. My riding on them was probably about 80/20 road/dirt until I got a separate wheelset for road tires.
For your intended use, I'd recommend them, they roll pretty well on the road and I never had a problem keeping up on club road rides. They are good on fire roads and decent trails. I find that I can't climb hills over 22%, because with the gearing on my bike I need to stand up at that point, and then the back tire loses traction and spins. I've also gone through some spots of loose sand where I wished for a bit more aggressive tread, but these spots are few and far between.
Don't write off tubeless. I probably have 3,500 miles on my All Arounds, I've had a few punctures in both but I've never had to dismount the tires to fix them, nor stop riding due to a flat, the sealant has taken care of them.
