FreeBSD disabled SNA by default for compatibility with pre-SandyBridge on drm-legacy-kmod (previously, in-base drm2), see bug 214593. SNA is also unstable due to I915_USERPTR_UNSYNCHRONIZED, so you may need the patch in bug 236003. While modesetting DDX (part of xorg-server) is recommended over xf86-video-intel the version in ports/ is very old (may lack some PCI IDs) and may have bugs with LIBGL_DRI3_ENABLE=1 (upstream default). So try both.
