JPEGs in the iOS Photos app are full size; when exporting, they are a fraction of original size. All export settings appear to be correct. See the attached screenshots. A 9MB photo exports to 721KB
Can anyone assist?

That is very strange. But the original image, taken with your Canon camera has a very unusual file size for a JPEG with a very small pixel size, just 2336 × 1558 pixel. With such a small width and height the jpeg should not be larger the 2 MB at most. Has the image been cropped, before you exported it? Or edited with an external editor, that is saving the edited version as a huge TIFF? That would explain, why the image in Photos is showing a huge file size and the that the exported version has a smaller file size. You may want to export the original image file with "File > Export > Export unmodified original" to check the size.

The problem was solved by the Genius Bar - the helpful guy changed the color profile on the export settings to "original" and that did the trick.
Here is the exported unmodified version, and it is still reduced vs out of camera. The above image was cropped in iOS Photos
Weird. When I export one 9.9 MB jpeg that's been edited, it becomes 4.4MB-- but it had lots of sky, so compression was very efficient. Another, a sports picture, was 12.2MB and it became 12.1MB. So it's all about compression. The picture you show has lots of solid background, so it should compress a bit, but I'm totally surprised at a factor of over 10! I agree, something sounds odd. I also tried exporting to iCloud disk, but that made no difference.
The dimensions are the same-- when you blow up the 700KB version, how does it look? Do you see lots of difference?
The 700KB looks decent, however if someone wants a print...it likely will not look good
