Giga or Sharpen for printing cropped images

Good afternoon. I not sure if I should be using Photo AI, Giga AI, or Sharpen AI. My workflow in Lightroom includes cropping a RAW image in LR created in a Canon 5D3 or R5 to varying degrees after using Denoise. When I do moderate to heavy cropping, then export to JPG for printing, I will often receive notification that the image doesn’t have enough resolution for larger prints and/or canvas.

To accomplish this, my question is, would Sharpen or Giga be the appropriate Topaz product to help this?
