A 100 uF capacitor proved sufficient, but a value up to 1000 uF reduced some harmonics further. With the amplifier stability solved, I turned to seeing how far I could increase the input signal. This depended on the supply voltage. With a supply voltage of 5 volts, the output started clipping with an input signal above 70 mV.
Basic understanding of ceramic capacitor voltage ratings.
Now there''s a lot of wiggle room in capacitor ratings, like how many can fail outright / violently (electrolytic), or how much the dielectric loses capacitance at voltage, vs. over time at ≈0 V (ceramic). So when you compare voltage ratings of dissimilar capacitors, the voltage rating seems almost arbitrary.

Why is a high voltage capacitor not a capacitor?
Operating a high voltage capacitor at lower dc voltage cause some low continuous current to flow through the capacitor, thus rendering the capacitor not behaving ideally as a capacitor. The voltage rating of the capacitor is the point at which the dielectric & insulation between the two plates starts to break down and fails.
Do power factor correction capacitors increase harmonic voltage and current?
The application of power factor correction capacitor systems can create unwanted increases in harmonic voltage and current unless the capacitors are properly applied with reactors, in series with the capacitor, to suppress harmful harmonics.
What is a leaky capacitor?
A leaky capacitor has the effect of a large rated capacitor that leaks and keeps the circuit from working properly. In most cases, you can over rate a capacitor and get away with it. If you double the voltage value of the capacitor but keep the supply voltage low you might want to also double the Farad value.
Are MLCC capacitors rated at low voltage?
You tend to find more like the opposite. A high voltage capacitor will have it's capacitance rated at low voltage meaning when operated close to it's rated voltage the capacitance will be much lower. This is why the different MLCC capacitor dielectric types exist, they guarantee a certain capacitance vs voltage characteristic (amongst other things)
Is a high voltage capacitor rated for 2x the working voltage a good part?
Rule of thumb round here is that caps rated for 2x the working voltage is a good (reliable) part. You tend to find more like the opposite. A high voltage capacitor will have it's capacitance rated at low voltage meaning when operated close to it's rated voltage the capacitance will be much lower.
