Rancho El Sendero. We stayed there in November and enjoyed it. Especially if you want quiet, I recommend avoiding La Posada, Homero's, etc. which are closer in to the park entrance and tend to have more late night party noise.
La pagoda is close to the canyon and quiet, generally. Of the 35 or 40 nights I've spent there there was only one loud night where some young guys in from monterrey rented a room and played music loud by the pool all night. Otherwise it's pretty sleepy. Last I was there was 2021 and the old rooms were $20/night, camping was $5
