New Heterodox Mono
Hao Chi Kiang published New Heterodox Mono on GitHub under the SIL Open Font License, with its copyright notice dating the work to 2019 and a Bold weight added in 2021. It is a rare thing: a Didone-flavoured monospaced serif built for code, adapted from Alexey Kryukov's Old Standard TT with the proportions reworked to fit a fixed pitch and the contrast reduced slightly for legibility at small sizes. Letters like f, r and j are deliberately unorthodox, and coverage is Latin only for now. If you need a monospace you can load straight from a CDN, these free typefaces cover the same register.

Quiet type that does the work
Body type does the heavy lifting. Get it right and the reader never thinks about it; get it wrong and they feel it before they can name what is off.

The display sets the register; the body follows through. When both halves of a pair pull in the same direction, the design disappears and the words come forward.
