I'd let it regrow and when it's nicely greened up give it a coat of glyphosate. after a couple of weeks (or whatever it sayson the packet) mow it all off. How much work you need to do on the soil depends onthe type of soil and whether you want a fine lawn or a playground for the kids.
when our kids were small we made a lawn in the very broadest sense of the word by mowing the weeds until the grass took over. This assumes some of the weeds are grass. Grass thrives on being mowed, but weeds don't. A lot of them will still be there but mowing creates a green space quickly if that's what you want
