I get big bags of native wildflowers and Johnny Appleseed style my yard, throwing them anywhere there is space. Now, I don't have any grass to maintain or anything so there's that...
I let them get big, flower, and then cut them down to the roots to fix soil. They come roaring back annually now. TONS of bee and wild pollinator action now after only 2 years. They really get kind of unruly and shade out my smaller bushes like eugenia seedlings but it appears that they help the plant, not harm it. They are healthier than ever.
There are a ton of benefits for me who has empty soil. It seems they hold water in the soil better, they are a source of organic material to fix the soil, and they take the brunt of the insect pressure. Sometimes an entire golden rod becomes an aphid factory... But they never go to my fruit trees. It has taught me to lean into IPM and allow for sacrificial plants that take the hit and get so out of control that predators arrive en masse. I have never had so many ladybugs, assassins, praying mantises etc!
