The typical advice for capture sharpening in Adobe Camera Raw is to set the Radius setting based on the details in a photograph.
For photos with lots of tiny details, a smaller Radius setting is often suggested. A wider Radius can obliterate tiny details. For photos with larger details and wider edges -- for example, portraits -- a wider Radius setting is usually preferred.
What if your photo contains both tiny details and larger features that can benefit from a wider Radius? You can capture sharpen twice, if you use ACR and you load your photograph into Photoshop as a Smart Object.
I produced a 7 minute video that demonstrates how to merge different capture settings for the same photograph with ACR and Photoshop. http://www.thelightsright.com/CaptureSharpeningTwice
