In math, -x² is -(x²), not (-x)². But as proposed for JS, -x**2 is (-x)**2.
PHP, Python, Haskell, and D side with the traditional algebraic
notation, against JS. Here's PHP:
$ php -r 'print(-2 ** 2);'
-4
Python:
-2 ** 2
-4
Haskell:
Prelude -2 ^ 2
-4
The D grammar:

What you're describing as sometimes tighter and sometimes looser I
would call the same precedence. It's even easier to specify than the
current proposal:
UnaryExpression : PostfixExpression **

That has different right and left precedence and is probably the closest to
the mathematical intent.
Not to quibble, but I do want to understand:
UnaryExpression : PostfixExpression ** UnaryExpression
