So far, I've not missed any features of Chrome except opening accidentally closed tab again. You might want to change few settings though: "show full urls" and "show favicons".
Apple Pay also works remarkably well, just click "Pay with Apple", and the authentication request pops up on your iPhone, requesting Touch ID / Face ID.
I've not seen anyone implement the new "Sign in with Apple", which automatically generates burner email addresses, but that's another reason to switch to Safari.
Also, one feature which I like is the automatic generation of strong passwords.
