I love your lists! There is always such a fun mix of games. As for August, I'm grasping at straws for themes, but you could do Awwwwww-gust. Cute games or games with cute art. Games that make you go awwwww.
Great lists! The only themes I can think of for August are the Dog Days of Summer (dog themed games🐕) or Back To School (I've got no game ideas for that, but August is when ppl stock up on school supplies)🤷♀️
