Doug Tallamy's Bringing Nature Home makes a convincing case for the importance of native plants to healthy ecosystems. (Hint: it's the insects.)
A strong reason to favor native cultivars is that the bred versions are bred for their appearance to humans. They are often sterile and devoid of nutrition or not attractive to the pollinaotrs, perhaps not quite as bad as paving the lot, but not a lot better.
Be very careful of the use of systemic pesticides. They are great (for some values of 'great') for keeping the nursery plants free of insect damage. They also reliably kill the insects that we want (i.e., NEED) to foster. Best option is grow your own from seed, or find nurseries that do not use systemic or persistent pesticides.
And yes - go to Xerces society to learn a LOT more!
Raptors might not have a preference, but pollinators do, and in the US that counts for a lot. Planting native species gives native pollinators a better chance against their more generalist invasive cousins, the European honey bee (A. mellifera) and paper wasp (P. dominula).
It's a good idea to do that, too, since there are a lot of species which native pollinators can pollinate, but invasive pollinators can't, which means these plants rely on native pollinators to reproduce. More than that, some native insects are closely enough coevolved with native plants that, in the absence of the latter, the former fail to thrive or die out entirely - monarch butterflies, for example, are struggling for this very reason.
Audubon's native plant finder is a good place to start - the email address is optional, all it requires is your ZIP code. https://www.audubon.org/native-plants
That said, being from Audubon, it's focused around serving bird species, rather than insects. For insects specifically, look to the Xerces Society, which is a conservation society parallel to Audubon but interested in invertebrates: https://xerces.org/publications/plant-lists
