Only about a dozen ships appear in the Clone Wars animated series, but when you also add in the computer games, X-Wing, Empire at War, Battlefront..., there are another dozen or so ships that technically are also Legends-level canon for the period.
Looking at the user modifications being released for Empire at War specifically, they also introduce about 20 more ships or variants into the Clone Wars that were only described in novels, or pictured in comics, but that were never actually modeled for rendering or released under the license. Those would be tangentially canon at best, but are great inspiration.
All of those numbers are just looking at the ships that measure at least 500 feet, and at 1:25000 scale the silhouettes of anything smaller really break down.
