As someone looking to exfiltrate my photos from Google, I'm about to trial Immich, and I really appreciate you sharing your experience. Sounds like it's a good next step for me.

There's plenty of tutorials but you can request a Google Takeout of your photos and then point immich-go at it. I can confirm that this works really well.
