How do you export or share edited Mac Photos keeping size, date and data

Are you sharing the photos with another Mac user? Then I would share the photos as a Photos Library. Duplicate your Photos Library and delete all photos but the ones you want to share from the copy of your library. Then share the cleaned up copy of the Photos Library. If you are using iCloud Photos, force a download from iCloud for the album you want to share, before you duplicate the Photos Library.

For them to stay in order in the Finder they must have sequential numbered file names or dates. Since dates is next to impossible to change and you don't want to the you need to do the following;

1 - collect the photos in an album and manually put them into order.

2 - select all with the ⌘+A key stroke.

3 - use this AppleScript to give them all the same title but with sequential numbers at the end so they will be sorted by title in the order you want: Batch Change Title to Text w/Padded Sequential Numbers.

The script compiled as an application can be downloaded from this tutorial site:  P01 - Applescripts from Photos’ User Tips Compiled as Applications  

4 - export the retitled photos via the File ➙ Export ➙ Export XX Photos. Export with the settings shown in this screenshot:

The result is that they can be sorted by filename and be in the order you want:

Export originals with .xmp sidecars (which carry the metadata you have changed inside Photos.app) and then join them in some 3rd party app.

The metadata from those sidecar .xmp files can be copied to the corresponding .jpg files with GraphicConverter 11.5.5 > File > Browse... > [select folder] > [select .jpg files] > IPTC/XMP menu > XMP Sidecar File > Copy into JPGs, TIFFs, PNGs, webp, HEICs.

GraphicConverter does not support copying .xmp to movies but you can use exiftool for that. Sadly Photos .xmp is non-standard (GraphicConverter bypasses the flaw quite well) so some hacks must be used to copy western and southern locations correctly with something like:

exiftool -overwrite_original_in_place -api QuickTimeUTC=1 -ext mp4 -ext m4v -ext mov -tagsFromFile %d%f.xmp -api QuickTimeUTC=1 '-AllDates<XMP-photoshop:DateCreated' '-Track*Date<XMP-photoshop:DateCreated' '-Media*Date<XMP-photoshop:DateCreated' '-Keys:CreationDate<XMP-photoshop:DateCreated' '-Keys:GPSCoordinates<$XMP:GPSLatitude# $XMP:GPSLatitudeRef, $XMP:GPSLongitude# $XMP:GPSLongitudeRef' '-Keys:DisplayName<XMP-dc:Title' '-Keys:Description<XMP-dc:Description' '-Keys:Keywords<XMP-dc:Subject' '-FileCreateDate<XMP-photoshop:DateCreated' '-FileModifyDate<XMP-photoshop:DateCreated' .
