While not inherently weak to magic, if we consider Captain Marvel or Black Adam's power themselves to be magic, it stands to reason that some or all of it might bypass Clark's biological invulnerability and thus he would take more damage in a head-to-head slugfest even if he's actually punching harder.
If you're thinking of video games or tabletop rpgs, imagine that Clark's not weak to magic itself but Black Adam has high armor penetration or some such. A lot of writers don't get that, though, so hurr durr magic is kryptonite.
