Adding on to this, newer iPhones have a ProRAW feature. Various tech youtubers have documented ways to create a shortcut in the Shortcuts app to automatically convert them to HEIF or JPEG, which might impose slightly less processing.
Similarly, ProRAW photos imported to Apple Photos on Mac can be reduced in processing by clicking Edit Photo, and then hitting Save Changes without necessarily changing any settings (or just changing something inconsequential would work too). Doing editing forces the Photos app to discard the preprocessed image embedded in the ProRAW and replaces it with a software processed version which I find slightly more natural. However, ProRAW is still processed by the phone, so you need to download a third party app and shoot classic non pro RAW (then use the same conversion shortcut maybe) on top of it.
