The buoyant force on a floating object is equal to the object's weight out of water.
If it's floating, then the buoyant force on it is exactly equal to its weight. (That makes the vector sum of the vertical forces zero, which is why the object is not accelerating vertically.)
If the object is floating on the surface of the fluid, like a boat, then the fluid is exerting the normal force on the object. The normal force is a force that is equal and opposite to the force of gravity acting on an object. If the object is under the water then the weight of the water above the object is pushing down on it.
weight, The weight of an object is the force of gravity acting on it.
The downward force acting on an object in free fall is Gravity.
The weight of a floating object and the buoyant force on it must be equal. If they were not equal, then there would be a net vertical force on the object, and it would be accelerating up or down.
Archimedes's principle states that the buoyant force acting on an object immersed or floating in a fluid equals the weight of the fluid displaced.

weight, The weight of an object is the force of gravity acting on it.
The upward force acting on an object is the normal force. It is equal in magnitude, but opposite in direction to the object's weight.
The forces acting on a stationary object are balanced. If you were to add up all the forces (taking the directions into account, you would get a total of 0. There are always forces acting on a object, such as gravity, so you cannot say that there are no forces acting on it. You can say that the forces are balanced.
The downward force acting on an object in free fall is Gravity.
The weight must be less than the buoyant force. Push down on a floating cork and it will sink below the surface. Stop pushing and remove your hand, and the cork's buoyancy will take over and the cork will float again.
The larger the force acting upon an object, the greater the acceleration of the object.
If the forces are balanced this means that there is no net force acting
