Looks like you've had your question answered, but I wanted to clarify a few points.
First, in Naples, most agents will use a NABOR contract and the NABOR contract has very specific provisions regarding the personal property that is to be transferred upon sale. As pointed out, best practices even when a unit as described as "furnished", is to attach an "Inventory" of everything that is going to be transferred at the time of the sale to avoid any last minute disputes. Make sure you review and read your contract with your realtor very closely and ask questions about what it means!
Second, its important to make a distinction between a "fixture" and personal property. A good rule of thumb for determining if something is a fixture is if you turned the house upside down, and the item remained attached, its considered a fixture. If not, its personal property. There are exceptions (as always) but under your example, those items would not stay attached, therefore are personal property.
Best practices is never leave anything open to interpretation (ie, what constitutes "furnished") and make sure you work with a realtor that will protect your interests.
