the planets you listed wouldn't work, humans are animals, and evolution is just genetic adaptation over the course of many generations, typically this change is brought about by the need to survive this is natural selection.
Other times these changes are brought on by sexual selection, like peacocks and the males tails feathers, they don't provide a easier way to survive, but they do make reproduction more likely so it still makes breeding down to the next generation more likely
Some evolutionary changes just happen to occur, and because they aren't harmful they're a new trait, think humans and blue eyes, blue ares are a pretty new trait, but they don't really aid or harm in chances of survival or the probability of breeding when looking at it over the course of many generations.
I'd advise picking (making up) earth like planets but with certain different environmental factors changed for example:
Less slightly less Oxygen in the atmosphere,
Replace the nitrogen in the atmosphere with another gas, (a non-toxic one)
Maybe make water rarer so people have adapted to use less water?
Maybe the planet is in tidal lock with its star, so one side always faces the sun, and is lethally hot, while the other always faces away from the sun, and so is lethally cold.
So the vast majority of humans live in the middle area where it is always twilight.
but maybe some groups have moved towards/away from the sun and have started, or have completely adapted to the cold/hot temperatures
