If you assume an "ideal" capacitor it would be, as you say, rather pointless. But in the real world, capacitors do not behave as "ideal" capacitors. Therefore you use two different types of capacitor to meet two of the two different goals of having the capacitor there ( such as voltage smoothing and avoiding high-frequency noise ).

Another reason when done in production designs is to reduce your bill of materials (BOM). If your design has loads of 100 nF caps but needs one ~50 nF, it is often cheaper to use two 100 nF''s in series due to the quantity you''re buying the 100 nF''s in, and also reduces pick/place setup time.

Furthermore, we will explore the effects of reversing the polarity of a capacitor and the potential consequences. Capacitor polarity is significant because it determines the
The larger the capacitor the less ripple and the more constant the DC. When large current peaks are drawn the capacitor supplied surge energy helps the regulator not sag in output. The white and black bars on the capacitor symbol show that it is a "polar " capacitor - it only works with + and - on the selected ends.
A bipolar capacitor is just a non-polarized capacitor. I think the term is usually in reference to a type of electrolytic capacitor to make it clear that you can use it in any orientation since they''re usually polarized.

Capacitor polarity refers to the orientation of positive and negative terminals in a capacitor. In polarized capacitors, the positive terminal (anode) and the negative terminal (cathode) must be connected correctly to ensure proper functioning. Conversely, non-polarized capacitors don't have this restriction and can be connected in any direction.
