I think to call it "Rounded" it would need to be... softer. :-)

I would not refer to it as "soft"; that's only good for selling toilet paper or bath towels.

Smooth.

depending on intended use, social might be an option nowadays, instead of rounded

Smooth is the word.

"Rounded" says semicircular terminals to me, which this doesn't have. I think "soft" is fine.

There's nothing wrong with "Soft"! (And anyway people love toilet paper.)

I call my FF Unit Rounded, because it is. That word is a participle, meaning something straight has been rounded. Nothing about the amount of rounding. There are typefaces called Round, implying that they do have complete semicircles for terminals.

True, on rethinking it my expectation of semicircular terminals is too narrow for the word "rounded." But at the same time I see Unit's curves as corners made into "quarter rounds," that is as arcs of a circle and thus also the same kind of "rounded" animal as a font with semicircular terminals. Satya's typeface to my eye is a different thing--more inflated than router-carved.
