For those interested or curious, I had a water pump leak and went ahead with a replacement of the ACDelco 252-800, which is supposed to be in improvement of the Ford/Jaguar part in our cars. Also $900 less than what the dealer is charging. This has a metal impeller as well as improved water pump gasket. I can keep everyone updated whether I recommend this fix or to stick with OEM. So far the garage doing the job said the car runs well and no leaks.
Pretty common water pump that is made by various manufactures. The AC Delco listed is probably one of the better ones, based on the specs I can find. Note that the ACDelco is for the 4.3L V8 engine's, as it is a one-piece design. The one-piece design is better (in my opinion) as it is one less area to potentially leak.
To list a few other ones below for cross-reference:
GATES 43503
BECK/ARNLEY 1312245
MOTORCRAFT PW448 (metal gasket that locks into place around the impeller.)
The 4.7L pumps have a additional tube that may be able to be transferred to the others I listed above as they are of a two-piece design. I added a photo below to show.
