How about not spraying poisons? How about not even having the lawn and growing either edibles or xeriscape native pollinator gardens?
If you need a lawn for play space or entertaining, leave the weeds. Clover is a support species that pulls free nitrogen out of the air and makes it available to the grass. Many other lawn "weeds" are very useful for lawn health, pollinators, or medicinal use. If the lawn area is thin, rake it hard with a metal rake to disturb soil, sprinkle appropriate seed for light and climate, then cover with a very thin layer of compost. Bagged compost is just fine unless your lawn area is huge, in which case see above ;)
If it feels very hard/compacted, hire a company to aerate before seeding.
I can't believe anyone in this community is recommending spraying poisons.
