Not quite accurate. xdvipdfmx can use PS fonts in .pfb format (in the
texmf tree) just like other dvi drivers; but I don't think it can use
"classic" LWFN-format PS fonts at all. It never converts type1 to OT
or uses that cache folder.
It's xdv2pdf that converts .pfb format PS fonts from the texmf tree
into .otf files and saves them in /Library/Caches. It doesn't do this
with LWFN fonts, but it should be able to use them if they're
installed in a standard Fonts folder.

xdv2pdf (not xdvipdfmx) does this with the fonts it converts and puts
into Library/Caches; they're just activated temporarily while the PDF
is being generated. No other software (including ftxinstalledfonts or
FontBook) will use these fonts, unless you manually install them in a
system Fonts folder -- which I would *not* recommend.
As for font IDs -- they're not fixed across restarts (or perhaps
logins?), and temporarily-activated fonts such as xdv2pdf uses may
have different IDs each time they're used. ftxinstalledfonts will
show the names and IDs for those that are installed in the system's
Fonts folders, but it won't know anything about fonts that a program
activates privately and temporarily.
