For A3 prints, I use a larger radius (around 2.2 pixels) and sharpen at 100% to 125%. Other sizes fall in between these values. I aim for sharp web images and prints without excessive sharpness.
Sometimes, I convert to LAB mode to sharpen only the black and white channel, preserving color information. Afterward, I convert back to RGB for printing. In recent Photoshop upgrades, this intermediate step seems less necessary, likely due to improved algorithms.
