Low volume plans compensate lack of volume with high intensity. If recovery is an issue, maybe you’re better off with longer slow rides to build base. You can check out Traditional Base with highest volume that you can allocate per week. Do not be alarmed by missing intensity. Did 6 week block focused on Z2 rides only and suddenly started breaking power PRs in sprint durations that I never trained for while starting from traffic lights in city.
Also, you can switch to different loading/recovery weeks pattern. Like 3 weeks of increasing load and 4th week for recovering. See Alternate Sweet Spot Base, Work : Recovery Week Layout
