This house was built in 1964. The interior walls are all wood panels. They
told me behind the panels are stucco walls with lathe, I am familiar with
wood studs and drywall sheets, but back in 1964 they did not have that.
So what is really behind those stucco wall? If I need to route cat5, or RG6
or electrical wirings I know what I can do with drywall and studs, what does
one do with this type of walls? If I need to hang shelves is there any firm
solid backing in the back to attach things to? There is no studs at all?
Drywall and studs had been invented and were quite common in 1964.
I seriously doubt that you have stucco walls on the interior. You
may well have plaster walls. Plaster walls are usually considered
an upgrade to drywall, even today.
Plaster walls have the same studs. The wet plaster had to have
something to hang onto while it was drying. The something used to
be wood lath, 1/4" thick x 1 1/2" wide slats nailed horizontally
across the studs with a gap to squeeze the plaster through. It
may be wire mesh, usually 28 oz., probably blued not galvanized.
It might be red gypsum panels with holes in them. It might be
blue drywall with no holes and a skim coat of plaster veneer, the
usual installation today.
Plaster is much harder than drywall. Plaster is usually thicker
Plaster can loose its "keys" with age, moisture, vibration, etc.

Gypsum wallboard was invented in 1917. By 1964 it was used in most
houses. My guess (and it's only a guess) is that your house is made of
gypsum wallboard nailed to wood studs with a stucco-like coating over
it, which is actually joint cement laid over the wallboard with a
thick-nap roller. Later, someone covered the walls with wood panels.
This is most likely what your wall looks like inside. Many older in
Florida had plaster walls.

I had a condo in Treasure Is Fla built in 1967 and it had stucco
walls. They used metal lath, over steel studs and slopped on the mud.
You can see what you have by taking off a couple electrical box covers
(turn the power off)
In a place between the edge of the cover and the box, scrape into it a
little. If it is grey cement and sand looking stuff it is stucco.
White, fine power would indicate plaster, pretty much the same stuff
for your purposes
Look around on the sides of the box at the top and bottom and you
should be able to see the stud and what that is made of.
There should be the regular hollow cavities between the walls.
If you have the wood studs it is just like drywall for hganging
shelves but you will need a masonry drill to get to the wood. You can
hang light stuff on the stucco but if it fails it will be ugly.
This is a surface that takes those little plastic sleeve anchors
pretty well for the small stuff.
