Is there any downside to using a larger than needed smoothing capacitor?
Or the 0.1uF may be for local decoupling to stabilise that regulator.

Capacitor
The capacitor recharge rate is a non-linear function—the rate at any given moment depends on how much energy is stored at that moment. Near zero and near full capacity, the recharge rate is very low, and it peaks at 25 percent. The important thing to remember is that the recharge rate declines dramatically once it falls below 25% of capacity.

$begingroup$ Since the circuit is at a constant potential difference and the pulling apart of the capacitor plates reduces the capacitance,the energy stored in the capacitor also decreases. The energy lost by the capacitor is given to the battery (in effect, it goes to re-charging the battery). Likewise, the work done in pulling the plates apart is also given to the …

What Happens if You Use the Wrong Size Capacitor? Is It Safe?
Larger capacitors typically have larger voltage ratings and hence cool down faster. It could also be due to age (caps shrink with age) or manufacturing capability.

5 Ways to Test a Capacitor
This method is not recommended because it only can be used to determine if the capacitor can hold a charge, capable of sparking when shorted, or not. It can not be used to check if the capacity of the capacitor is within the specifications. Using this method on larger capacitors could result in serious injury or even death!
