The A320 normally lands with flaps full, flap 3 is generally for abnormal procedures (like an engine out). I generally want some flap out (usually flap 1) as I start descending on final since the drag keeps the speed under control.

There are five flap lever positions on an Airbus which correspond to six different configurations. For an A319 or A320NEO these are identical except for the flap angle in Config Full, which is 40°.
Pilots usually use Flaps 1 when the weather is good for flying and if the runway used is longer than needed. Flaps 2 is used usually when headwinds are not strong enough or the runway in use is not that long for a takeoff run.
I think the typical landing speed for an A320 is around 130 - 140kts or 150 - 160 mph. The landing speed varies per the weight of the aircraft, altitude of the airport (Denver is very high compared to Los Angeles) and the weather conditions.
Most airlines IRL use Flaps 30 as the standard. It would go something like (1/5/15/25/30) 40 is used when there are higher wind conditions of the sort to try and stablize the aircraft on approach.
So a Flap 3 landing would be a landing with the flap handle in the Flaps 3 position, one short of full extension. Why would a pilot want to do that? The ideal landing speed would be a little higher than with full flaps, which might be advisable if the winds are gusty and the runway length is not a constraining factor.
