> i wonder if you could implement the ide functionality you want with a 'wrap' menu of popular functions that are applicable to the thing to the left of your cursor

This is already implemented in IntelliJ for Java - they call it "Postfix Completion". For example you can type ".cast" after an expression to wrap what's before the cursor in a cast expression, so type "a + b.cast", then pick cast to "float", and pick how large a preceding expression you want to cast, and you can end up with "(float)(a + b)" and go from there. They have postfix completion that can extract expressions into variables, create if-statements and switch-statements from expressions, and so many more things that I wish I had when doing non-trivial Python coding in my IDE of choice (which is not by Jetbrains)...
