Am I missing something here? I just tap and hold on watch face and swipe left/right to choose another watch face.

I don’t see what exactly is missing here.

Looks like yes. I’ve noticed the same. In fact, hyperlinks etc. are also green - the only place blue color remains now is blue ticks (after message is read).

That green shade is bit tacky - should’ve been a bit subdued. And it looks much worse with dark mode.

I have screen protector and case (AWU2). It makes already bulky watch even bulkier but I’ll settle with bad looks rather than scratches. And I’ve bumped it quite a few times.

Same for me. If I wake up, it still shows it as core sleep.

Further, my sleep tracking ends with sleep profile - e.g. if my profile ends at 5:30 AM and I wake up at 8:30 AM then it shows I slept only till 5:30 AM.

Worse part is, the data between 5:30 AM and 8:30 AM is stored with Apple, but visible only with 3rd party apps.

I’m running developer beta on iPhone and Apple Watch. Not facing any issues.

In fact my experience has been that issues are pretty quickly fixed on developer beta versions and those versions are quite well tested and not that unstable (in fact I don’t recall last time I had any issue because of beta version).

One thing you lose (that I’m aware of) is capacity to write reviews on app store. It is allowed only if you are running stable ios version.
