Get the Monument device, attach as much external usb storage as you want and watch it do pretty much the same thing Apple Photos does but locally on the device. iOS and android apps. More than one user — my fam uses it. Plus you can backup the files to any SFTP storage. And the usb drives can mirror each other too. Highly recommend. https://www.getmonument.com/

Does the Monument device have the option to share albums/folders across the Internet? Do I need to open a hole in my firewall for this?

Edit: I've reached out to the Monument team as well.

Works really well with families - each person can have the app installed and it’ll bring all photos onto the device. Yes you can share photos and albums. Yes you need to make a firewall config, otherwise you’d be hosting elsewhere in the cloud. There’s no way around that.
