Thanks for your replies so far—very insightful!
Re Folha vs. Floris:
[De Groot’s] most original achievement (…) was the spirited headline face designed for the Brazilian newspaper Folha de São Paulo. Folha differs from his other original typefaces in that it has strong vertical stress. (…) In 2001 De Groot designed a new headline face for Le Monde, which was named Floris Newspaper after his son. Floris is a continuation of Folha: it has vertical stress, narrow forms and a somewhat rectangular oval as a basic shape. The family is now much larger. It comes in seven weights, from Extra Light to Black. Its regular works well as a condensed text face. (Jan Middendorp: Dutch Type.)
And:
In 2007, Floris was redrawn as part of a drastic redesign of the German weekly Jungle World. Floris JW is a headline family in weights, from ExtraLight to Black. The Jungle World project also resulted in Floris Text, a new typeface for publications, which is still under development. (LF Floris on lucasfonts.com)
