Huh, just yesterday I started setting up and getting used to my new (to me) Apple Watch Series 6, after having used a Pixel Watch 2 for several months.
I'm surprised to find myself somewhat disappointed, and preferring my Pixel Watch, though I'm still giving myself some time in case it's just familiarity. But a few things:
* The available watch faces are pretty underwhelming, particularly digital ones. There's only a single one that actually includes the seconds, as far as I can tell. And the only one with lots of complications is Modular, which sticks the time in the corner, and has a big unwieldy complication in the center. My kingdom for Pixel Watch's Utility.
* No watch face store!?
* I can't seem to set up a minimal all-red face for night time, like I had on the Pixel Watch.
* The heart rate complication is just a picture of a heart that I click and it takes me to a widget that measures my heart rate. I had a real time glance on Pixel Watch, right in the complication, always up to date.
* The sleep tracking is weird and confusing. I need to set up schedules and such? On the Pixel Watch, it just tracks my sleep automatically.
* Subjective, but I still like the size and shape (round) of the Pixel Watch more than this Apple Watch, for now.

If you switch to Sleep focus (side button, moon, Sleep) it'll switch to a more minimalistic face and turn off the Always On Display. A quick tap on the screen would still show the time.
I bought AutoSleep [1] back when in the day when watchOS still didn't have sleep tracking, and still use it daily. It's fabulous for automatically tracking naps.
I know you won't like this answer, but you probably want the Ultra. The Modular Ultra watch face does the things you want. Heart rate on the screen, lots of complications (six small ones, one big one in the middle), seconds displayed in several possible ways. Screen turns red automatically in the dark.
Sleep tracking should be pretty much automatic. I don't have any fancy schedules configured, although maybe at one point the phone did ask me what my usual sleep times are. It just automatically collects sleep stats and puts them in the Health app.
The round watch face preference is definitely a subjective thing. I can't imagine how it works as a practical matter since so much of what makes a smartwatch useful benefits from the rectangle form factor and space.
