Ente is a service that provides a fully open source, end-to-end encrypted platform for you to store your data in the cloud without needing to trust the service provider.
Ente Photos is a paid service, but they also offer 5 GB of free storage, and there is the option to self-host yourself too.
It has built-in machine learning, much like Immich has. What may be more unique is their Legacy option, allowing pre-determined family members or friends to gain access to your account if you have passed away.
