You might be referring to very processed satellite images, but AWS has many more satellite/aerial data sources than GCP in their Open Data program

Those are way too low-res for typical satellite map usage, though. It doesn't even look to have a pixel/house resolution, even.

Well it depends, it's true that Landsat is only 15m resolution, and Sentinel is 10m, but if you only need US-coverage, NAIP is 60cm resolution.
