I should explain what I've tried. Nextcloud photos is not a photo application. It's basically a shared gallery with thumbnails. There's no metadata support or editing. No true multiuser access other than granting sharing through Nextcloud like Dropbox. The only good part is you can autoupload from your phone. I've looked at several webapps, like Piwigo. Most of them feel like a single user application or have limited upload and metadata support. The closest I have found is Digikam using external SQL, but this requires a local application carefully configured with a DB and a fileshare.
