In the result of a difference, I'd like the "+" sign to
be displayed whenever the result is positive (just like
the "-" sign is for negative results).
Is there any number format that would do that?

Something like the Custom format "+0;-0;0" without quotes.

Change 0 to whatever precision or format you want, e.g. 0.00 for
effectively Number with 2 decimal places.

Drop that last ";0" if you want +0.
