I didn't completely replace grass with clover, but instead seeded clover and let the two commingle. it doesn't grow as tall as grass, doesn't leave bare patches, is a nitrogen affixer so the rest of the lawn looks even greener without fertilizer, and it attracts pollinators.
The only catch is that it spreads fast, so if you have a vegetable garden you'll need to work more to keep it out of there. However it's much easier to pull too.
Pick a type of clover that is native to your region.
