We found the nifty PAM8904, which is an amplifier specifically designed for driving piezo elements - and unlike audio amplifiers it's good for up to 300 KHz! It's a switched-cap piezo driver that has bridge-tied load (BTL) output and up to 3x voltage multiplication thanks to a built in boosting circuit for up to ~13Vpp. We whipped up a quick breakout in our 2mm JST-PH STEMMA form-factor to make it easy for anyone who wants to beep their boops very loudly.
