Check Airman, #15, "…
why not just turn it off."
The landing flare is a pitch manoeuvre; use pitch control for adjustments.
The OP is concerned with a possible firm touchdown; this is minimised with pitch control.
Providing the flare is commenced from the recommended point - appropriate parameters, and using the recommended procedure then the touchdown will be safe - safe; not necessarily soft.
Aircraft are certificated for a range of flare circumstances, wind-shear, speed error, with speed / alt / energy margins similar to flaring from Vref -5 depending on type.
Don't invent new procedures to minimise circumstances which have already been considered in certification. The crews' primary responsibility is safety; a safe landing, not necessarily a soft landing - which many passengers do not understand or don't perceive the same factors as the pilot - familiarity or location to cg.
