You've got everything that you need in Synology. * Use Time Machine to automatically backup your computer to Synology NAS * Use SMB Share to manually manage big files or archives when you need it(use rsync if you lazy) * Use CloudSync(synology app) to automatically back up your Google Drive to your Synology * Use Synology Photos to (semi)automatically backup your photo library form your phone to your NAS * Use Hyper Backup to backup your NAS to the cloud using S3/Backblaze B2/rsync. One thing that might be missing is auto transcoding. 223J might not have enough power to transcode videos, but if you get somehting similar to DS920+, it can do transcoding for you. I've got mine setup with Jellyfin container, and it plays very well because CPU can transcode that.
