HRV is indeed a good proxy metric for sleep quality, and I can really recommend Garmin watches for measuring it. Even the cheap models track the "Stress" metric 24/7 (which is HRV under the hood). More expensive ones have pulse ox monitoring and a full blown sleep analyzer that provides sleep stage breakfown and a compound sleep quality score. All from just being worn on the wrist normally through the night.
However, HRV is not the whole story about sleep quality. If you develop sleep apnea, for example, your HRV will not react very much, though your sleep quality will suffer. There is no substitute for sleep study to detect such issues.

Sometimes I wake up refreshed and felt like I slept very well, only to have my Garmin tell me that I had poor sleep quality (usually because of too little REM sleep), other times I've had a bad night of sleeping (like the dog needed to go out several times) and I wake up tired, and my watch congratulates me on good sleep quality. I wonder if one of the sleep monitors that uses a pad on the mattress would be more accurate.
