I would link to the downloads in the opening paragraph.
My impression is that while legible it is too fat. You'll notice that Fira Code and JetBrains Mono are similarly wide -- and narrower than Atkinson Hyperlegible Mono.
I'd recommend getting it from there rather than the Braille Institute's website since they require an email and EULA, but here's the other download link anyway.
With Nerd Fonts, I'd recommend downloading both and setting up a fallback system through fontconfig though. Unfortunately, some versions (Nerd Fonts, official download) are still missing the backtick/grave glyph.
I'm pretty much there with you. I tend to use Fira Code for the improved visibility, but really would prefer Consolas/Inconsolata, but there are a few character variations that I don't like as much and it's slightly harder to read (for me). I also have come to rely on the Nerd Fonts enhancements with my terminal prompt (Starship).
