Link to the actual Fira Mono homepage: https://github.com/mozilla/Fira
The Fira family - https://en.wikipedia.org/wiki/Fira_(typeface) - https://github.com/mozilla/Fira
To a lesser extent IBM Plex - https://en.wikipedia.org/wiki/IBM_Plex
And a genuine classic in the the Eurostile family https://en.wikipedia.org/wiki/Eurostile
Fira Mono link seems to be no longer served(redirects to general style guides page). Maybe you could link https://github.com/mozilla/Fira instead?
I love Firacode and use it in Android Studio/IntelliJ but it has this bug[0] where "=" is invisible in Gnome terminal. So, I had to switch to Fira Mono[1], the parent of Fira Code, from Mozilla. Fira Mono doesn't have cool ligatures but it's a good font and works pretty well.

I've used Inconsolata exclusively (the original first [1], then the -dz variant [2], then the -g variant [3]) since 2002 or 2003.
I've recently switched to Fira Mono [4], designed by the awesome Erik Spiekermann for Mozilla.
