Could just use bigger screws. For wood holes you can plug the hole with wood glue and toothpicks, then just screw your fasteners into that.
If you need more holding power, nearly anything you would use for drywall will work for this. If you are needing to get through the wood + drywall behind I would prefer flip toggle bolt.
Ok. Just for future reference. You don’t need to drill holes in pine like that if the screws aren’t near the butt end of the board. And pine is soft enough any screw will go right in.
Also you pre drill holes don’t have to be so close screw size. You only need a hole like half the size of screw.
But for your current problem you can either move the mount over 1-2 inches left/right or up/down.
You could just move it over, and try to cover the holes with what you are hanging. If you want it there, you could drill out and glue in corresponding dowels. Allow to dry, chisel and sand flush with surface. Drill pilot hole and screw. If what you're hanging isn't too heavy, typical wall plugs will work fine as well.
