I’m sorta in the same boat as you. I run Synology all my photos and manage 5 different family members photos.
So I have different use cases for them and myself.
**For them: **They only care about the ability to see where they took their photos and its uploading correctly. The built in face detection is average at best but its enough for them to find the photo they are looking for.
They will never use the full extent of all the metadata that is available to them if I had it.
The tradeoffs are the ease of deployment and account management. I only have 5 members and if I had to teach each one which website or page to go to so they can view their images, it would drive me nuts. I simply give them credentials and a link to download from Apple Store and Playstore and off they go. New phones? No problem. Add it to their AppleTV? Don’t need to bother me.

For Me: **
I use Excire Foto and it scans each photo and helps me manage everything with a very powerful AI tool for tagging. I use it for the majority of my photo management. The downside, its not very remote friendly. So if you’re working remote, you will not be able to manage your NAS photos from afar.
This way I keep both Synology Photos and use Excire when I’m needing to do some real work.
May I ask why you export and de exify photos? Synology Photos does this work for you.
