You can use the stock Google Pixel camera app without Play Services or internet access, it will produce the same photos. Tje only thing that won’t work is the small image preview at the bottom left with the last image you took, clicking on it will just tell you that Google Photos is not installed.
The GrapheneOS camera app is probably the best FOSS (sleek/minimal) camera app I’ve ever used, image quality isn’t quite at stock Pixel level, but still pretty good, actually.
