Why does a floating capacitor act differently than a grounded capacitor?
So the circuit will look like two capacitors in series, connected to ground, one capacitor being much larger than the other. Capacitors in series add together like resistors in parallel. So the overall capacitance will be slightly less than the small stray capacitance. So it will take very little charge, way less than case 1, as you surmised. ...
Flexi answers
Grounding a capacitor involves connecting one of its terminals to the ground or earth. This is typically done using a wire. The ground serves as a reference point and helps to stabilize the voltage across the capacitor. It also provides a path for the discharge of the stored energy in the capacitor, which can be important for safety reasons.

HVAC Start and Run Capacitor Explained and Replacement – …
A Start or Run Capacitor can be combined into one capacitor called a Dual Capacitor with three leads but can be split between two separate capacitors. The Start Capacitor gives a fan motor the torque it needs to start spinning then stops, while the Run capacitor stays on, giving the motor extra torque when needed.
A Fundamental Rule of Grounding (EE Tip #124)
Figure 1: Botth sections, A and B, may be on the same PCB with separate ground planes (e.g., analog and digital). The diodes and the capacitor between the planes limit potential differences due to ground bounce, etc. Broken lines inside boxes 1 and 3 indicate ground referenced, non-symmetrical inputs and outputs.
Grounding and Decoupling: Learn Basics Now and Save Yourself
High frequency power supply noise is best reduced with low inductance, surface-mount ceramic capacitors connected directly to the power supply pins of the IC (typically 0.01 μF to 0.1 μF). All decoupling capacitors must connect directly to a low impedance ground plane in order to be effective.

Why Your Capacitor Bank Should be Left Ungrounded
Figure 1 is used to illustrate how a grounded capacitor bank can interfere with the ground fault protection system of a resistive grounded system. The main concern arises when a capacitor fails as shown in Figure 1 by the "X". Since medium voltage capacitors fail shorted, a faulted capacitor is like applying a line to ground fault on the facilities
Grounding and Decoupling: Learn Basics Now and Save Yourself
In the last column we highlighted the importance of maintaining a low impedance ground plane to provide a path for digital and analog return currents. This StudentZone article discusses the equally important and related topic of power supply decoupling to maintain low impedances at the points at which power enters the integrated circuit.
capacitor ground or not?
Regarding your original question about capacitors: "Ground" is an arbitrarily selected reference point that means 0V. ANY point in a circuit could be declared as the 0V "ground" point without affecting how it works. In general, absolute voltages never mean anything - all that matters is the voltage DIFFERENCE between the two terminals …
