I think git annex assistant might work well for you. I have a terabyte of photos and videos. I use git annex (without the assistant) to store and manage them. I push a copy to my desktop computer at work and to the NAS at home. I'm not much of a believer in using the cloud for archival and backups. Hard drive space is much cheaper than the cloud, even with lots of redundancy. I just purchased a cheap external drive which I'm going to use for offline backups in the fire safe. I also have a friend who is willing to set up a backup-swap with me, but I need to sneaker-net the first backup to him. Git annex will push to the cloud as well, I don't use that because I don't want to pay for the storage space. For the photos on my phone I'm using resilio sync plus a cron job to copy them off and then free up space on the phone. For organizing them I use a react/rails web app that I've been developing on and off for a few years. It's similar to google photos (without the AI).
