I've had my peace lily for about three months now, and I'm still figuring out its watering preferences

I've had my peace lily for about three months now, and I'm still figuring out its watering preferences. It droops dramatically when thirsty, which is honestly kind of helpful, but I'm worried I'm overcompensating and keeping the soil too wet. Does anyone else find Spathiphyllum wallisii a bit dramatic? Also, I noticed it finally sent up a new leaf last week, which felt like a tiny victory. Should I be fertilizing it during the growing season, or am I okay just with regular watering?
