Wow.  Currently SGC sti(4) is tested only on 425e, and
sti(4) on 425t is one of todo list items.
(I have 425t but it has only DIO topcat)

> Booting the netbsd-GENERIC kernel via NFS, and using serial console, I see the sti(4) driver come up and recognize the 1280x1024@8bpp framebuffer attached via SGC, and it looks like wscons wants to use it (or is using it), but whenever I've tried to boot using local console I get nothing.

Could you post full dmesg on the serial console?
How did you setup to get screen console?
In that case which console is used on bootloader?

There is a console detection code in sys/arch/hp300/hp300/audoconf.c:

 https://nxr.netbsd.org/diff/src/sys/arch/hp300/dev/sti_sgc.c?r2=%2Fsrc%2Fsys%2Farch%2Fhp300%2Fdev%2Fsti_sgc.c%401.2&r1=%2Fsrc%2Fsys%2Farch%2Fhp300%2Fdev%2Fsti_sgc.c%401.1
but maybe there is some quirk on sgc sti(4) on 425t.

One problem to get Xorg server is there is no information to
control color palette of sti(4) framebuffer.  I tried to write
RAMDAC registers directly but it looked some more sti(4) specific
control was required.

Note drawing framebuffer against sti(4) on 425e using mlterm-fb worked:
