"As the saying goes, you cannot serve two masters."
I recognize that saying from one specific real-world religion. The one you were raised in, perhaps? Do all the gods in all D&D settings follow the teachings of that particular religion?
The range of answers to this question, follows from the range of religious beliefs of the forum participants. Those who were raised in a religion and don't actively practice it, still tend to hold deep assumptions based on its teachings.
Wonder Woman has gifts from six deities: "Demeter, great strength; Athena, wisdom and courage; Artemis, a hunter's heart and a communion with animals; Aphrodite, beauty and a loving heart; Hestia, sisterhood with fire; Hermes, speed and the power of flight." If Wonder Woman isn't welcome at your table or in your setting, then that's your choice. I'll find her a seat at mine.
As a player, I find that Oath of Ancients and Archfey Patron go together just fine.
