I can do most of that on my Garmin. Really only stuff that requires mic is not doable because it doesn't have a mic. And I guess notifications "with images". Heck some of it like 2FA I did on my Pebble!
The only thing I really hate about the Garmin is that they kneecap CJK support by region locking it.
This reminds me: it's silly that the Apple Watch eSIM has to be from the same provider as one's iPhone, and some providers which offer a phone eSIM don't support provisioning it for the Apple Watch, and vice versa.
