Since sedges (the yellow nutsedge in your first question) and grassy weeds are treated with different herbicides and your lawn is more than 40-50% weeds, renovation may be in order.
Please take time to read through our publication on Lawn Establishment, Renovation, and Overseeding, which outlines the step-by-step process in detail. https://extension.umd.edu/sites/extension.umd.edu/files/_docs/programs/hgic/HGIC_Pubs/lawn_pubs/HG10...

If you decide to renovate your lawn, the first step would be to do a soil test to find out your current pH and nutrient levels. You can find information about soil testing here: https://extension.umd.edu/hgic/topics/soil-testing Starting from bare soil will allow you to amend your underlying soil, if needed, with lime and/or organic matter. This will set the stage for the successful establishment of your new turf.

The best time to establish a lawn is in the late summer – early fall. The next best time to seed would in mid-March through April. For full sun lawns, turf-type tall fescue is recommended for most situations. Recommended cultivars tested by the University of Maryland are listed in this publication. https://extension.umd.edu/sites/extension.umd.edu/files/_docs/programs/hgic/Non_hgic_pubs/TT-77%20Re...
