While I haven’t ascended to fully cursive coding, I do actually enjoy Fantasque Sans for this very reason.
It manages to kind of connect the letters in some ways that my eyes can better see single words as “tokens”. After using it for a while, going back to a regular monospaced font looks like a speadsheet of unconnected letters.
Also
Ctrl + w
to delete one word backwards (which is what OP wants to do)
