Does this work with Pex?

Of course, it can work with Pex.

is it possible to unscrew the barbs and put a different size barb on it?

It may be difficult to divide the barb. If you really need to replace the barb, I recommend you this products(ASIN: B07XK1LW6J). The Male thread is 1/2"

Is the interior diameter of the valve plumbing 3/8" or a more restricted in size?

The OD of the barb is a little large(about 1/16inch/1.58mm) than 3/8 inch, but it suitable for 3/8 inch ID tubing indeed. It can connect with the tubing more tightly, but the tubing should NOT be too hard, otherwise the barb may be difficult to insert into it.
