Ca t'en fait 3, tu as le choix...

Je ne sais pas s'il existe vraiment des règles formelles, mais, à ta place, j'essayerai d'apprendre par l'exemple.
Tu visites le thème "Basiques" (Sérif ou Sans Sérif, suivant ta police) en ayant coché l'option "voir les variantes" qui te permettra de voir les polices ayant une vraie version grasse. Tu en repères une ou deux qui te conviennent (tu les testes dans un texte pour voir si ça donne bien l'effet que tu souhaites) et tu étudies les différences entre la version régular et la grasse dans ton éditeur.

Tu as, par exemple, la Clemente http://www.dafont.com/fr/clemente-pd.font?af=on qui existe dans un nombre impressionnant d'épaisseurs différentes, ce qui te permettrait de bien ajuster le rapport que tu recherches toi-même.

C'est un avantage du format TTF : tu as en quelques sorte le "code source" dans la version utilisable, tu peux donc aller y farfouiller pour l'étudier en détail.
