For RDAs there is one paper that may be what your thinking of https://lemm.ee/post/51272940 "Priority Micronutrient Density in Foods"
There's a huge difference between what can be measured in food, and what the human body can use from the food. And the paper looks at what is actually usable. It has graphs with different food stuffs so you can compare.
You can use food tracking apps that break down micronutrients like cronometer, but these do not take into account bioavailability.
