The original Modular watch face is still on Apple Watch Series 4, and it's definitely more minimal than Infograph.

The full-motion watch faces such as Liquid Metal can go full-screen or be shown in a smaller circle with added complications. But it's always with analog watch face hands.

How gold is the gold? It's more bronze-ish, and it's growing on me -- but I still wouldn't get gold.

Coming to the Apple Watch Series 4 later this year is FDA-cleared ECG, via an embedded electrical heart-rate sensor that requires touching the crown for 30 seconds to complete the circuit. More testing on that in the future.
