Yep, a monthly full drive read or even better a scrub with verification of the filesystem's checksums is great. It's not often enough to seriously impact performance in production or meaningfully increase the rate of read disturb errors, but it will allow the SSD to catch data degradation before it becomes a real problem, and to refresh any data that starts showing elevated error rates (or take other measures like start adjusting read voltage thresholds for that block). I don't actually have a cron job set up for it, but I tend to scrub my SSD array every month or two when checking on free space and SMART logs.
