I recently mounted 32mm Gravel King slicks on Dura Ace C24 wheels, 15mm internal, and with latex tubes. What a fantastic ride. I did have 26 mm on the wheels, tried the 32 out of curiosity. Sure, the handling and acceleration are a bit slower, but that matters not to me.The high level of comfort is well worth that trade off for me.
I put the 26mm Gk’s on a set of Hed Belgium Plus rims, 6800 hubs, internal width is 18.2 mm. The tires spread out to a hair over 28mm, and they feel like a different set of tires with improved ride. I do not notice any difference in handling or acceleration.
IMO, both changes worked out to my benefit. The C24 and 32’s are on my Soma Smoothie, the Hed and 26’s are now on my Airborne Zeppelin. The Zeppelin gained about a pound due to 32 spoke wheels, the Smoothie’s weight evened out.

The Zeppelin is strictly pavement, the Smoothie gets some easy multi-surface rides, mostly cinder and hard packed dirt, some pea sized gravel, packed sand.
