How to finish sous vide carnitas without drying them out
Make sure not to break up the meat too much. In particular, try not to smear it between the fork and the dish... You want chunky pieces, not spread-out strands. The more broken and strand-y the pork gets, the greater its surface area and the faster it dries out. You also want to crowd the pieces in the pan as much as possible while browning. It's better to have a bunch in the middle of the baking pan, than individual pieces spread around the pan.
