Yes. It matters lots and lots and lots.
For several reasons....
A fish will usually have quite a large volume, but they are very skatey and will feel unstable to someone not used to a shortboard...
...but you'd be able to catch waves easier with a fish than a shortboard.
A fish is best in smaller waves, while a shortboard works better in more powerful/steeper waves.
Despite its volume, a fish can be difficult to paddle (its large area at the front means its pushing a lot of water) and can be hard to duck-dive (tricky to get that fat tail underwater).
A fish isnt very forgiving. Going from a mini-mal to a first shortboard, I would get a softened shortboard (I dont mean soft. I mean non-extreme).
something like isaluteyou's suggestion of 6'6" x19x 2 3/8 is about right - with a squared off tail, reasonable volume in the rails and not too ridiculously pointy.
