Speed impact of tire options? Hoping for advice

Riding a canyon grail on its stock 40mm tires and they are ready to be replaced.

Where I ride this bike is about 50/50 pavement and category 2 gravel. They do well in the gravel. I feel (though I know feels not the same thing as data) they are slow on pavement. Certainly louder, haha (than my GP 5000 on my road bike).

Looking to better understand what some options might be? I know gravel kind opinions are wildly all over the place in this forum. Are there tires that have some more “slick” in the middle a good option? Or would I regret that when I’m in the gravel. It’s literally 50/50 as in the route I usually go out is the background gravel way and then after a coffee I take the flat road back home.

All that said, any recommendations on a balanced tire would be great. I used to ride this bike on some single track kind of stuff but not anymore, so at least I can find the best tires for the way it’s ridden.
