“Valeur” is by no means restrained to monetary value : asking the Wiktionary (in French), only its 4^th sense is that of price, coming after the quality of something, nobility, and importance (interest).

^{The 7th sense (a rule of one’s ideology) is also probably of interest for you (your question made me think of it at first).}

Answering more directly your question, the English Wiktionary — aside from “value” — gives another sense to “valeur” : “valor”, i.e. bravery, courage. Again, not so monetary.

• Is there an alternative ?

Interestingly, the French Wiktionary for “value” first mentions “mérite”, before “valeur”.
