I don’t have much knowledge of options as I’ve just stuck with what I’ve known for a long time now.
However, as you and your wife have an iPad, you could consider iCloud Photos that’s part of the Apple ecosystem to see if it suits?
I haven’t used it with a win pc for some years now (I use a Mac) but it is meant to work with a pc as well as Apple devices. Adding photos to whatever folders you have permitted on your pc will sync with the cloud (and be stored there) and then synced with any connected devices (eg your wife’s iPad and your back up pc). Any edits on any of the connected folders will sync but be careful as that means deletions as well (though with Apple you have 30 days to recover).
On my Mac I actually have folders that I don’t allow to sync with iCloud as I store lots of raw files as well as JPEGs that I don’t want to sync for various reasons like they duplicates, still to be processed, etc. This allows a me to keep a separate backup direct on my Mac/offline Ssd as well as the iCloud for synced photos.
At 90Gb it is above the free storage that apple provide and so would cost £2.99/mth for the next smallest package (200 Gb).
Personally, I’ve found it easy to use and (except the initial bulk upload which can a considerable time) is fast and efficient in its syncing. The iPad’s native photo app had good editing features and will sync back edits to the Mac (or your win pc) and your wife can upload to Instagram or whatever from the Photos app supplied with the iPad.
