Best overall: Garmin Venu 3. It is the strongest smartwatch pick if your priority is sleep, HRV, and stress tracking because it combines nightly HRV status, sleep score/coaching, stress tracking, Body Battery, good battery life, and broad smartwatch features without needing a subscription for core wellness metrics.

If you train seriously, choose Garmin Forerunner 265 instead. If you use an iPhone and want the best app ecosystem, choose Apple Watch Series 10, but expect weaker native sleep/HRV interpretation and much shorter battery life. If you want the simplest recovery-focused experience, Fitbit Sense 2 is easier to understand, but it is less complete as a smartwatch than Apple or Garmin.
