> 1) I have no xorg.conf.  That is good as far as I can tell.

Good. If necessary just configure desired sections. Since the adoption of KMS
by various vendors DDX drivers like xf86-video-intel are deprecated.

No. "video" group is required for DRI3, VAAPI, OpenCL, etc.

See also https://dri.freedesktop.org/docs/drm/gpu/drm-uapi.html#render-nodes

> 3) Do I need to add kern.vty=vt to /boot/loader.conf?

Default since FreeBSD 11.0, see base r268158.

> Do you want me to attach the /usr/local/etc/X11/xorg.conf.d/xorg.conf before I try the ""AccelMethod" to "SNA""

Find which one specifies "Driver" "intel" and adjust "AccelMethod" there e.g.,

  Section "Device"
          Identifier "integrated_card"
          Driver     "intel"
          Option     "AccelMethod" "SNA"
  #       Option     "TearFree" "true" # uncomment if *not* using compositor
(e.g., picom)
          Option     "DRI" "3"
  #       BusID      "pci:0:2:0" # uncomment if multi-GPU
  EndSection

Find which one specifies Section "Device" then "Driver" "modesetting".
Alternatively, remove all configs and xf86-video-intel.

Auto-configuration is known to be broken. Try with empty xorg.conf(5) then fill
in whatever you miss. modesetting(4x) usually works fine without any
configurion.
