Question about any ecological or environmental benefits to heirloom plants

We have native plants and invasives. Native plants almost always have a superior beneficial impact on the local environment and ecosystem in terms of food for urban wildlife, diversity of life, reduced water consumption and water runoff, etc. Separate from the native versus invasives distinction, I wonder whether there is any observable urban wildlife benefit between contemporary pants versus heirloom plants. I have heard of heirloom apples, potatoes, tomatoes, and roses and I am sure there are many other forms. In fact, I saw heirloom tomatoes in the local grocery store just the other day. In my brief reading on heirloom plants, while there is acknowledgement of the benefits arising from their fitness for local circumstances based on their evolutionary history, I am not seeing any discussion about whether there is a environmental or ecological benefit. I assume that heirloom plants may put less stress on the environment by being more resilient in the face of weather variation and may require less water but I wonder if that is correct. Anybody know?
