For deer, I don’t think it matters much, especially if you’re shooting a .25 and up. Light if you want the trajectory, heavy if you’re more concerned about energy, but they’ll both kill a deer with the right shot placement. Obviously with bigger game like elk it would be preferable to get a heavier bullet, but I think bullet construction matters more than weight. Especially with the .308 150gr copper bullets i shoot now, length wise they’re similar to a lot of 165s and they’re tough enough to still give me more penetration than I ever got with softer, heavier bullets.
