There are few things in my mind, which is the best fiber optic cable or copper cable. I need help for the clear about this point. which is the better and faster connectivity cable?

In a home situation, fiber is almost never required. In a datacenter setting, there are advantages of fiber. It is lighter weight, smaller diameter and may have a tighter bend radius. If you have hundreds of cables in a single spot, like a large router, fiber cables can be easier to manage.
LONG distances are the another benefit of fiber. You can run 10KM on a single mode fiber pair. Fast ethernet (100Mbit) can go 2KM on multi-mode fiber.
Bundled fiber (100s of strands in a single sheath) are beneficial for building-to-building (or floor-to-floor) connectivity. The material cost for pulling a single pair of fiber, vs a bundle is minimal. The pulling labor is the same. There is extra labor required to terminate the bundled...

For what usage?

Fibre optic cables have faster transmission speeds and less loss just by their design. I'm sure there is plenty of literature to explain better than I.

For almost everyone who comes to this forum the answer is nothing.

The key reason fiber is used is to go longer distances than is possible with ethernet cable. Ethernet cable can go 100 meters. It would be rare to need a connection more than 100 meters. It is mostly used to connect between location not within a building.

There are other very specialized needs where you must use fiber but in general since you can run 10gbit over cat6a copper cables the speed of the connection is not the main concern.

But having spare fiber or multiple networks traversing the distances is very useful in a business setting.
