What if Superman was a Muslim? (fanfic)
Alternate take on Batman v Superman: Dawn of Justice

"Typical" vampire can be taken out by a determined middle aged bloke of average fitness with a hammer and a pointy piece of wood. If Superman is in trouble against that sort of opponent...best to read Tintin.
Armed with a holy water atomiser she'd be able to account for a few.
Really main two questions with Superman v Vampires ought to be:-
1/ What effect would his heat vision have on them? Would it be equivalent to sunlight?
2/ Would he be comfortable about killing intelligent creatures? Or would he be impelled to restraining them till he could find a cure?
Captain Marvel's strength comes from magic. Depending on the writer, that may help a little but they are about equally matched. Same with Black Adam. There was a Silver Age story where a demon punched Superman so hard it knocked him to the other side of the planet. He flew right back and punched the demo even harder.
Given Superman's strength and speed, it's ridiculous that a vampire would have any chance even if it's supernatural origins somehow make it a little stronger against Superman.
But the sheer inconsistency of how Superman's "magic weakness" works is yet another mark against it though it's largely the same inconsistency that always happens with the abilities of comic book characters.
