I haven't seen any good guides for individual and household preparedness, but I think that this guide "Interim Guidance for Preventing the Spread of Coronavirus Disease 2019 (COVID-19) in Homes and Residential Communities" (https://www.cdc.gov/coronavirus/2019-ncov/hcp/guidance-preve...), especially the precautions section, can be a useful place to see what would be needed to prepare.
Some things to have besides food storage and a normal supply of medicine would be to have cleaning supplies, maybe gloves and rubbing alcohol, and perhaps face masks. One issue is that face masks may be good to keep available for those who need it most. I'm not sure what is best practice to ensure you aren't taking face masks from healthcare providers or someone more in need.
