So I was recently delighted to notice that if I use Camera RAW to
convert PEF image into a JPEG in Photoshop, the resulting JPEG
contains all the original EXIF data, including lens type.

DNG Converter preserves all the data. Extracting the .xmp data from a .PSD file after RAW conversion with "File->File Info..." command, here's what you get, as example:

...
      <rdf:Description rdf:about=""
            xmlns:aux="http://ns.adobe.com/exif/1.0/aux/";>
         <aux:LensInfo>280/10 1050/10 32/10 45/10</aux:LensInfo>
         <aux:Lens>smc PENTAX-FA 28-105mm F3.2-4.5 AL[IF]</aux:Lens>
         <aux:LensID>4 38</aux:LensID>
      </rdf:Description>
...

xmp is not EXIF, it's much more complete than that.
