Sorry, but no IDE comes with a proper 3278-like font. Not even IBM's Developer for z/OS comes with one (they commissioned that other font called Plex... who would take seriously a font named after a media player?).
That is delightful. I remember using 3270's back in "the lab" in high school ("alt-pf2" twice to compile!), and marveling at the individual phosphors on the screen. (When I could see better, for sure.)
Luckily, everyone can get one at https://github.com/rbanffy/3270font.
Note: shameless plug ;-)
