I feel like sublime text got most of it right and every editor since then has been a reskin of the same (just written in a different stack)
Since the original post was about a TUI editor, its worth mentioning Helix which supports most modern language out the box. That's amazing and wouldn't have been possible 10 years ago.
For terminal based, there are also many options but not so much in the direction of "VSCode style". They're mostly focused on being "vi-style". And also the huge file support isn't as good in any of the others that I've tried.
