Thank you for sharing your experience... Mine was a bit different. I still own an iPhone 8 - my Android / CalyxOS transition is ongoing... Usually I use the migration assistants (Android or iPhone), or iTunes on Windows - also easy: Just the Finder on MacOS. BUT: I once customized my ringtones to play Super Mario Bros - and I liked it so much, I wanted to keep them. Getting it to work was a lot of work (creating m4r files < 30s and putting them on the phone was a nightmare of error messages and many different tools). But there was NO way of extracting these back from my iPhone. iTunes did not show the files and crashed. Same on MacOS. No App on the phone had access to the files (e.g. to send it via Mail) - so I was stuck. This way was the ONLY way to get the files back. Like you, I did not have the correct file names, but renaming a few ringtones was acceptable. I heard of someone extracting the photos using an App like for Wifi file transfer (starting a little webserver on your phone), but fortunately, Apple Photos worked for that in my case.
