If you have a fescue or hybrid fescue lawn, there is no product better that turflon ester.
Its expensive, about $25 for 8 oz but a couple ounces will cover a decent sized lawn.
Unless you have an acre or more, a bottle should last a year or more.
Put an ounce in a hudson sprayer, add a couple of gallons of water, a few drops of kitchen dish washing liquid, (my trick) and spray it sparingly on the lawn. It'll kill almost everything except the fescue over a couple weeks.
Once in the spring, once in the fall, it it keeps everything gone even Bermuda and St. Augustine and clover.
It's not available at big box stores but I can find it at nurseries.
