Sunday morning (July 21) and Monday morning (July 22) will both be good times to image the Apollo 11 landing site. The early mornings will be better since the moon will be close to the meridian and thus higher in the sky.
I've made a finder chart using NASA's Moon Phase and Libration for 2019 showing the location (marked with an asterisk) and the simulated lighting for both nights (at 4AM PDT). On Monday morning the lighting will be pretty shallow (for the western U.S.) and that should make the features stand out. In fact, the simulated image clearly shows the "Cat's Paw" feature which is probably the closest crater to the landing site that can be easily seen from earth (using a small to medium sized scope).
