If she needs to have a divine father, it may be more interesting to make it a strange one, for story purposes.
examples:
Fetket, Egyptian god of bartenders
Koalemos, Greek god of stupidity
Äkräs, Finnish god of fertility, cabbages, and turnips
or perhaps Darkseid, God of Tyranny.
I'm opposed to any father for Wonder Woman, but if she absolutely must have one, Prometheus is honestly the most interesting suggestion I've seen. He works thematically--to a degree--and he won't overshadow or diminish Diana.
None. Having a father is not a good it for WW lore.
