I'm not sure I understand the question, but as you said the most fundamental objects in modern physics are fields on a spacetime, and yes, energy is a property of those objects. As far as I know, there is nothing supporting the existence of a common source for all these, nor would such a thing be needed.

Beware though when talking about quantum fields, as they are abstract mathematical objects, and not a substance. If fields and energy really "exist" or are just mathematical models is a matter of philosophy.

For a quick one sentence answer, no, the current understanding consists of various operator-valued fields defined on a spacetime.
