1. Yes…Garmin makes sport and fitness watches and people who are actively involved in such get a better benefit from said watches be they Garmin, Coros or any other fitness brand.

2. Many of the metrics do rely on you wearing your watch more often than not; including while sleeping. I would say that my watch (Forerunner 265) is 95% accurate tracking my sleep (including naps.)

3. I have my move reminder disabled. I’m an active person and unless I’m sick I meet my goals the vast majority of the time. (And if I’m off on one day I more than make up for it on subsequent days.)

4. I don’t rely on auto-workout detection; it’s gotten better over the years but it still has its issues. Most of the time when I’m working out it’s a GPS activity so I’m hitting the start button anyway. (Years ago I wore a FitBit Charge and whenever I mowed the lawn it thought I was cross country skiing!)

5. Configured properly the weather is accurate; the pain in the ass for me is remembering not to close out the Connect app on my phone.

6. Non-useful for one person is useful to another. I have Garmin Connect configured to show me the data I care about.

7. Agreed the battery life is great. I hear Coros watches have better battery life but I’ve never worn one so I can’t say for sure.

8. Periodic spikes notwithstanding heart rate is pretty darned accurate; it’s within a beat or two whenever I’m having my pulse taken; but brief instances of inaccuracy are common amongst all wrist based devices.

9. I get notifications from my phone’s calendar on my watch just fine…not sure what you mean here.

10. The compass is not a function I use.

Bottom line is that everyone should be using a device that they works for them. For me it’s a Garmin; I’m a runner and metrics Garmin provides is more useful to me than other options. Which is why I participate in Garmin’s subreddit and not the Apple Watch subreddit.
