I updated my watch to WatchOS 9. Thank goodness I can still have the same watch face, though it's been renamed from "Infographics Modular" to just "Modular."
I still like Modular Compact; my only complaint is I wish it had one more small complication so I could display the date, temperature, and battery, while using the large complication for schedule.
California is new, and while it is analog I think it is an improvement, as there is only one tick mark per second along the circumference which I thinks makes it easier to read.
Infograph is analog, but you can display a small digital readout of the time with seconds, although it will be blocked as the minute hand sweeps around.
Followup: Actually, modular compact has a disadvantage I didn't appreciate before. When I glance at it, it takes me a moment to see if the seconds are at zero or turned off. So I'm going back and forth between Modular and California; California is analog, but having tick marks at 1 second intervals really helps.
Followup 2: I'm happy with modular with digital seconds turned on, and the large complication in the middle used to show the next event on my calendar.
