Google Takeout (takeout.google.com) should give you almost everything in one place. It's a good idea to do this periodically in case you don't get the 30-day notice. Be prepared to download a few dozen GB, though. And there is no "incremental" option.
Takeout is nice, but I am surprised by the lack of features in other products that would easily allow to import the data from Takeout format.
I wanted to migrate from Google Photos to iCloud. Turns out there is no easy way how to import the photos to iCloud without loosing metadata. I gave up and just bought more storage on Google.
I agree with you there. All the data is right there, in fairly open (if not exactly standard) formats. They even include an index document and basic descriptions of the data formats. One would think their competitors would want to make it easy to port exports from Google Takeout into their systems.
I'm a bit surprised that you had trouble importing photos, though. Isn't most of the metadata kept in standard EXIF tags in each file?
