Nothing that would really make sense to move. Maybe the thumbnail cache, but you would lose it every reboot, and in that case it'd probably make as much sense to turn off thumbnail caching entirely.
SSDs don't really wear out that quickly these days so my advice is not to worry about it. By the time an SSD wears out through normal usage, you'll be able to buy one that is much larger and much faster for a small amount of money. They typically last into obsolescence now (unless they randomly fail, but if that's going to happen it's going to happen anyway). Worrying about them too much will cause you more stress than the actual problem itself.
