My advice is to talk to your fiancé about it! While it’s ultimately your choice because you’re an individual, you’re entering a committed partnership where you’ll be making decisions together.
I think it would be worth it if you only need to move for a year. It would give you and your fiancé time to grow as individuals before joining your lives.
While I think you should go for it, I think the decision ultimately comes down to whether you think the pros outweigh the cons.
