All good thoughts and suggestions by Kevin. I can also imagine that the designer started with Times Modern EF (one of the mentioned typefaces related to Denver Serial), but shortened the middle bar of F and blunted the corners. This font used to be available from Elsner+Flake once, and Bartosova does use other EF fonts on her website.
Given that Kristina Bartosova, who created the identity, also does hand lettering and type design (Sestra), I'm guessing that this is custom (not finding a match).
Denver Serial comes close for "ell," as do its related typefaces.
For the F, Al Evagrande comes close. Alto Adige has a similar vibe, as do Eksell Display and Superior Title
