Very nice presentation. One thing to add, all these things only fix symptoms. Fix the cause: Change the switching frequency to outside the human hearing range (>20 kHz)

If replacing a single filter capacitor with several smaller ones in parallel, I would suggest using several caps, each with a different capacitance` - Maybe select 3 to give an audible C major chord (C, E, G)
