Not really. For the quality of the shift Campagnolo fell way behind in the 80's and finally got their cassettes right in the 90's. In the 90's and 00's their shifters had the best ergonomics and were the nicest to use by far since they allowed multiple shifts in both directions. Since then though Campagnolo has only competed on aesthetics and weight, and really fell behind with electronic shifting.

Depends, if it's deep enough you might not be able to ride through it on anything short of a fatbike with buoyant tires. But in general, you ride through sand and loose surfaces by rolling into it with at least some speed and a loose grip on your bars.
