Cousine is a nouvelle typeface* to me, it ticks all the boxes, with dotted zero, good Il1 recognizability and minimal serifs.
It looks well balanced, I might give it a spin.
As my use of a monospaced typeface is 99% for coding, an important part of evaluating a new one is checking how it fares against a dark background and colour syntax highlighting. Some very beautiful typefaces become tiring in no time with those extra constraints.
*Pedant’s note: we are discussing typefaces, a font is a typeface in a specific rendering as in size, weight, italic etc. E.g. Source Code Pro is the typeface, SCP 14 pt, medium, italic is a font in that typeface. But this is an already lost battle…
