On the General > Storage there are some options I have on my iOS (v 11.3):
- Offload Unused Apps
- Auto Delete Old Conversations
Or I can manually offload apps one by one.
I think you are referring to the iCloud Storage settings on the iPhone when talking about deleting photos from all connected devices.
Probably the confusion is because they decided to put two storages: General > iPhone Storage (managing local storage) and Accounts > iCloud > iCloud Storage.
The last one (iCloud Storage) manages the iCloud so if you delete something from iCloud it will delete it from all devices.
Old conversations actually used to be the worst offender for some users - it included all media sent or received in those conversations which could be really hard to track down.
