This article covers crops you can plant until mid-July. I found this very useful. I have procrastinated filling up those holes left by things like lettuce, cabbage, kale, radishes-so this is inspiring to me!
Thanks to Our Stoney Acres for this very informative article which tells about Zone 6, where I live in Northwest Arkansas. https://ourstoneyacres.com/what-can-you-plant-in-july-and-still-get-a-harvest
The list includes: Kale, summer squash, cucumbers, beets, summer lettuce, and bush beans.
If you live in another zone, here is an article that covers them all–also by Our Stoney Acres. https://ourstoneyacres.com/what-can-you-plant-in-july-and-still-get-a-harvest
