What are your thoughts on finding a good level of subscriptions for online services, such as storage, photo backup, music streaming, video streaming?

Personal situation: I don’t want a ton of subscriptions. I take lots of photos. I listen to music quite a bit. I live in a household that has Android, iOS, iPadOS, MacOS, Linux, … and a Synology NAS that is already filling up with old music and video stuff from before streaming, phone photo backups as well as the photos from the big camera (manually copied so far). I currently pay for two cloud storage thingies and have to free ones, 3/4 are full :P We also have Spotify Family and cut down to only (HBO) Max and public service for video plus sometimes getting something specific for a month or two.

Any experiences or other observations welcome as well!
