So I tried a few things and concluded the following:

1) "--sar 2:1" works the same as "--video-filter resize:1920,2160,2:1 ..."

2) Resizing, though not necessary, also does not consume any time.
- Resize 1920x2160 lanzcos: 10.39 fps
- Resize 1920x2160 fastbilinear: 10.39 fps
- No resize (sar 2:1 only): 10.39 fps
- Resize 1904x2144 lanzcos: 10.73 fps
- Resize 1920x1080 lanzcos: 15:59 fps
3) Confirmed my Samsung TV (JU series) doesn't auto switch to 3D for the 1920x2160 sar 2:1 file, although it plays fine by manually switching to T&B mode.
- FULL Mode, 1920x2160 sar 2:1: NO auto-3D
- HALF mode, 1920x1080: Yes auto-3D
- FULL Mode, resize 1920x1080 sar 1:1: YES auto-3D
I don't think there is anything we can do about the auto-3D.
