What kind if soil do you have to work with? Sandy, clay, loamy...alkaline, etc... Sometimes the weeds that are flourishing can tell you what ails your soil, or what kind of nutrient profile is there for plants to feed on, so letting us know what weeds dominate can narrow the soil type down
Bee garden, absolutely! I have butterfly beds, bee beds... The more flowers to call beneficials, the better, and pretty much ALL herbs or flowers have some sort of medicinal or nutrient that benefits both animals and people
Borage is a HUGE bee magnet. Bees all over, and the flowers are edible and great vitamin punch; my chooks don't touch them, so they're good for something they wouldn't eat that can stay healthy for the bees... Gallardia is another good one, as well as lazy susans and echinacea.. Bee balm, anise, and even cilantro self seed readily, and comfrey, nettles, dill, and wormwood are all great bee/beneficial/medicinal herbs that grow rampant around here.
I literally just toss seed where I want them, and water every day until I see seedlings, and then I never put down seeds again. If they grow, great. If not, ok whatever
most times they grow, set seed, and migrate to where THEY want to be rather than where I want them, but sometimes they're a wee bit smarter than we are about selecting the right soil for the right plants
