I've had my Spathiphyllum wallisii for about four months now, and I'm still figuring out the watering rhythm

I've had my Spathiphyllum wallisii for about four months now, and I'm still figuring out the watering rhythm. It droops dramatically when thirsty, which is honestly helpful feedback, but I worry I'm either overwatering or underwatering depending on the week. My tropical climate keeps things humid, which seems to be working in my favor. Does anyone else find peace lilies fussy about water quality, or is that just me? I'd love to know what others have learned with theirs.
