Small Fiberglass Boat - Redoing the floor

Sooo... exactly how much give should I expect in the exterior hull? I can push in a bit. Feels like the fiberglass is solid but there's either no backing or possibly rotten backing. Is it possible the hull is solid fiberglass with no wood interior or is this thing just trash?

that really depends on how thick the hull is, and the type of resin used. I've had fiberglass flat bottom john boat style hulls you could push in with little effort, the sides were a little over 1/8" thick and epoxy resin.
If it's a single layer under 1/4" I would expect deflection.

Your going to need to get in there to see how bad it is, I did a 18ft walk thru windshield several years ago cause the floor got spongy. After cutting the floor top out with grinder I found 2 stringers rotten, fixed everything, took all the foam out cause it was water logged, refilled with 100 bucks worth of pool noodles layed new plywood and never looked back. Yours looks a lot less involved than what I did.
