Self-host and use Photoview [1], it has face recognition. I use this since 2 years with 5TB of photos (on ZFS) and it works flawlessly. It is worth it - everything under your control and you decide when to migrate. My phone's photos are also uploaded automatically to a Nextcloud folder, which is read-mounted to Photoview and scanned automatically.
