Moving to sf - storage or sell stuff?

I'll be moving from the east coast to sf in the spring as a single person with a dog and not much stuff. I'll be staying with a family member while I look for a job and a place, but they don't have room to store my stuff. Are my only options getting a short term storage unit or just selling everything prior to moving? The thought of having to buy literally everything on top of finding a place to live and a job feels very overwhelming. Is there anything I'm not considering?
