Download them from privacy.apple.com However, it should take a few days to get the .zip files with the photos, but they are the same uploaded to Apple servers.
Data Hoarder
We are digital librarians. Among us are represented the various reasons to keep data -- legal requirements, competitive requirements, uncertainty of permanence of cloud services, distaste for transmitting your data externally (e.g. government or corporate espionage), cultural and familial archivists, internet collapse preppers, and people who do it themselves so they're sure it's done right. Everyone has their reasons for curating the data they have decided to keep (either forever or For A Damn Long Time (tm) ). Along the way we have sought out like-minded individuals to exchange strategies, war stories, and cautionary tales of failures.
OP, for the future if you also have Amazon Prime, Amazon Photos provides free and unlimited storage for photos, including RAW.
Not free for videos though…which sucks
unlimited storage for raw or even prores video would be insane. iPhones can record 4K60 at 2gbps so even casual users can consume terabytes each day, only limited by their upload speed
