San Francisco is fantastic, but you can't use it outside of Apple platforms. Anything in this style better than Inter, even commercial? Graphik, Circular, Neue Haas Grotesk, Proxima Nova have been popular at various times, but are not as refined and versatile. Some brands have custom fonts that come close in my opinion, but they keep them to themselves.

The question becomes more interesting when you want specifically typefaces for UIs. One of the main qualities of San Francisco imho is the versitality and amount of cuts/versions specifically with digital screens in mind. I think thats not very popular segment with type foundries.
For example Klim type Untitled is in my eyes one of the best UI typefaces. But it doesnt have the breadth (i guess it wasnt that popular to dedicate the time). So you might have to pick their other typeface Sohne which is not made specifically for UIs (although it works just fine because Klimt is top of the top in the craft). There are things like FK Grotesk, Post Grotesk, Rooobert... there are many which work well and have the breath but are not specific to UIs either. This does not matter as much anymore because of hidipi screens though.
And also its not like Inter has ever been specifically optimised/hinted to lowdpi screens (not unlike all the SF, Arials, Verdanas, Helveticas of the world).
So Inter is not the best but its good enough and its free.
