My workflow is don't delete after import but format the card in the camera afterwards. I have XXXL cards and it is not such a problem if I forget to format.
I had one case where I screwed up a shoot and thought file corruption might have been involved (it wasn't) Even though I had formatted the card with the camera and shot maybe 5 test shots I was able to recover most of the images with Disk Drill

which has both Windows and Mac versions and looking at a sample of them confirmed it wasn't corruption, it was user error.
