One important effect of clarification is removal of some nitrogen content. This results in a slower fermentation, which is an important factor in increased production of volative compounds.
The effect of clarification is covered in detais in this paper:
Influence of cider-making process parameters on the odourant
volatile composition of hard ciders
https://onlinelibrary.wiley.com/doi/10.1002/jib.197
Effect of must clarification on cider odourant compounds
The principal purpose of clarification is to
remove cloudiness from cider and to remove components that
could have a negative impact on colour and taste. Our results
show that clarification also affects the volatile composition
of ciders [...] majority of clarified ciders were sensorially
characterized as fruity [...] in contrast with unclarified
ciders
Personally, I always clarify the juice prior to fermentation.
In addition to the increased aroma profile, I also believe that
such this treatment lowers the risk of excessive H2S production.

I do small scale batches only.
I add pectolytic enzyme and let it stand in a normal temperature. Usually it takes no longer than 12-18h to get following effect:
If I am in a hurry, I heat the juice (with enzyme) to 50C - then I get the same in 1-2h.
I suppose cooling the afterwards would further increase the
effect, as more particles would drop - but I never felt a need.

I have read in this group about debourbage, but the goal of that seems to be to reduce pectin for a clearer product, and not for any benefit in flavor, unless I am misinterpreting the information.

Currently I am using a product named "PektoFruit", but this may
be a local brand avaliable only in Poland.
What makes it different from majority of other enzymes is that it
is "designed" for apples and similar fruits - while plenty of
other products are for grapes.
The dosage is ~1-2ml / 50L.
From global manufacturers, german Erbsloeh offers enzymes dedicated for apples.
However the below picture may give an impression of a very clear
juice, it is still slightly cloudy. In my experience, there is
still plenty of yeast remaining, even after heating to 50C, to
start a natural fermentation within a couple of days. Adding 1/2
SO2 dose slightly delays the onset, but does not inhibit the
fermentation, at least in my experience.
