What is Considered Appropriate Monotheism?

Hello, I’m not jewish, I’m a former christian. I was looking into The 7 laws of Noah and I considered them rather interesting and consider ethical Monotheism to be essentially what I believe.

I’ve been searching around and have found that according to some rabbis, if someone were to follow these laws properly it must be done with the idea that they were given to all Mankind by The G-d of Israel specifically? The first law being the prohibition of Idolatry.

My question as someone who is not jewish and doesn’t know much about your religion and ways, is what is considered Idolatry? If I were to believe in a Supreme Being that created the universe and that all things emanate from this being in a somewhat similar way to Neoplatonists, would that be acceptable according to the laws of Noah or would that be Idolatry?

For example, if I were to believe that there are various aspects or understandings or cultural manifestations of this Supreme Being, whether it be Zeus, Odin, Shangdi, Lugh, or what have you, would that be considered idolatrous? Obviously I wouldn’t be worshipping the Supreme Being as multiple gods, merely that I believe it has many different faces or names that aren’t just the Tetragrammaton. I suppose it’s more Monistic than just strict Monotheism if that makes sense?

That being said, are there any religions today that would he considered Noahide compliant? I have heard some rabbis say Islam would be the closest, while others extend it to any form of Monotheism even Monotheistic Hindus and the like. Thanks for any help or insight!
