I don't believe Buddhism negates all reality of God, or concepts we might use to communicate that reality, personal or otherwise. One could call the underlying reality of the universe, compassion or generosity, "God" for example.
And compassion nourishes every thing. Non-duality doesn't negate a personal experience of compassion either. It calls us to a more accurate realization of wholeness or connection. But then so do some experiences of the divine.
I wasn’t being specific about any particular religion, but yea, I agree with most of what you’ve said.
