While a funnel-shaped depression of limestone eroded by rainwater is called a limestone pavement or a doline, a cave is a naturally occurring underground void typically formed through chemical weathering and erosion processes such as the dissolution of limestone by acidic groundwater.
If too much limestone dissolves in an underground cave, it can weaken the structural integrity of the cave and lead to collapse or sinkholes. This process is known as karstification and can occur over a long period of time as water continuously dissolves the limestone rock.
I'm not really sure what you had in mind. Given that the cave is in limestone (as the vast majority of them are) there has to be a dimensional limit to the dissolution and erosion processes. The floor is there by default: it is the lowest surface along a passage at that given time in the cave's development.
The ground-water is a solution of calcium carbonate it has dissolved from the limestone above the cave. The mineral is subsequently precipitated as deposits of calcite in the cave: stalatcties & stalagmites, and flowstone on the floor and walls.
No, a funnel-shaped depression of limestone dissolved by rain is called a sinkhole. A cave is a natural underground void or cavity that is typically larger and more complex in structure than a sinkhole.
Mammoth Cave is a limestone cave system, located in Kentucky, USA. It is a type of karst landscape, characterized by the dissolution of soluble rocks like limestone, resulting in unique underground formations and passageways.

Howe Caverns is a cave located in New York, near Albany. It is thought to be at least a million years old and is made of limestone.
it is a 'karst' cave, i.e. formed by the action of water on limestone.
From dissolution and erosion of limestone by acidic water over time.
Ellison Cave was formed by the erosion of the rock by water over millions of years. The cave was created as groundwater seeped through the limestone bedrock, dissolving and creating intricate passageways underground. Over time, the cave continued to grow and develop into its current size and complexity.
Limestone doesn't exactly "help" a cave unless the stalagmite's and such are what you are looking for. Limestone is what creates those.
Limestone caves are sometimes called solution caves because they are formed through a process called solution weathering. This occurs when water containing carbon dioxide dissolves the limestone rock, creating cave systems over time. The dissolved limestone is carried away in the form of a solution, hence the term "solution cave."
Jieta Grotto is a limestone cave it is not man-made.
Level 45 in the lake cave is nothing but limestone.
