I know that I'm not flying my velocity yet, but from my 20 years of flying, speed is your friend. I never flew an approach close to stall speed. I always added at least 10 knots above stall speed down the approach and if the winds were gusty, I added another 5 to 10 knots to my approach according to the gust value.  I would bleed this additional air speed as I crossed over the threshold to begin my rotation. As I entered into ground effects I would continue to slowly rotate until my aircraft was ready to land. I could land my Mooney so smooth that the mains would make a light scuffing sound as they touched instead of a screech. I have been asked to expedite my approach by the tower because of faster traffic in the pattern, and have landed at 100 knots. The key is to continue to fly the aircraft all the way until your airspeed is below a speed that your aircraft could fly.

Yes, plus the elevator "flap" effect.

Yes.  However my power off stall is a mush.  I would be less comfortable rounding out
if the nose were bobbing significantly.  With 2 up front I get a very gentle, barely
perceptable oscillation which does go away in ground effect.

I did a stall test according to the procedure posted by Scott B several years ago
which calls for setting up at 80 kn and pulling back on the stick to get the stall.  I
got a mush and concluded that was satisfactory, but probably at my aft cg limit.
I want to emphasize that I believe elevator position is very important.  I believe
that for the stall test, had I not pulled back on the stick and instead used my trim
button, I would have achieved a lower speed where the main wing would have stalled and
the canard kept flying (deep stall).  This is just theory as I'm not willing to try
it.  This is my reason for recommending never to trim for level flight at a speed less
than 80 kn.
