I’m by no means an expert on satellite orbit selection, but from my experience as a consumer the quality and frequency of imagery for an area has to do with a variety of factors - how often the overhead pass occurs in daytime vs. nighttime, how much data capacity they will devote to downloading the imagery, and what angle they point the sensor at.
Here’s a real world coverage map from a European earth observation mission, you can see they were able to select and orbit that gives them daily coverage of Europe but only biweekly coverage of Africa: https://www.researchgate.net/profile/David_Slater12/publicat...
Thanks, nice to see a map. But all those lines which stop at the mediterranean coast... those satellites surely cross north africa at almost the same time of day, it's just not marked because they are turned off? As you say, perhaps limited by daily bandwidth (or perhaps power?)... but that sounds like a commercial consideration.
