Sorry, I don't have that little Fuji flash.
Nonetheless, the Bessa III / GF 670 doesn't support TTL flash so a dedicated Fuji model is of special no benefit.
For what it is worth, a Metz 20 has about the same power and a couple of auto modes. It has a tilting head behind which a business card can slide behind for bounce indoors with a little forward fill.
I like it with my 35mm rangefinders and my 120 folding cameras when I want a small kit but know that I might be running out of light.
