My message history for 15 years or so is taking up like 2gb in messages my local storage shows, and attachments are taking 20gb, with a list sorted by size of the largest ones if I want to remove them. Not sure how it works if you save a photo or something, i figure it would get offloaded to iCloud like the rest eventually.
