CRJ-200 First Officer reported a hard landing in turbulence and crosswind conditions. The aircraft was inspected for a hard landing.

Narrative

Our aircraft experienced a possible hard/firm landing event on Runway XXL. At the time; I was the Pilot Flying (PF) while the Captain was Pilot Monitoring (PM).In the lead up to this event; we were performing the approach in visual conditions; with the autopilot on (used the RNAV Y XXL as the back up in the box); and the reported weather conditions at ZZZ were reported from the west (about 240 @ 7). The descent was slightly bumpy with minor variations in airspeed which required minor power adjustments; and worked to keep the speed slightly above VREF (Reference Landing Speed) to as a safety margin. The approach remained stable at the 1000; and 500 foot gates and was continued. The bumpiness in the air remained through this portion and more so north of the runway near the parking lot and structures where some surface friction can be observed. The autopilot was turned off just prior to the 'plus hundred' call to hand fly the airplane for the touchdown. As we approached 100' I started adding slight back pressure to slow down the closure rate and initiated the flare maneuver at about 30' feet to prepare the aircraft touchdown. I kept the power setting until about 20' where I initiated thrust reduction while correcting for the crosswind on the right side of the aircraft. By 10' thrust was already at idle and landed shortly thereafter (firm/hard). I proceeded to keep the centerline and directional control and slowed down the airplane to exit by [Taxiway] 1. I did apply additional back pressure to keep the airplane from sinking in the absence of thrust; but in my estimation the pressure seemed to have been a bit inadequate on this case; and may have contributed to the firm landing event.The flight concluded normally and at the suggestion and guidance from the Captain; Maintenance was called to initiate the hard landing inspection procedure.Cause: Energy management; over-reliance on automation; ADM (Aeronautical Decision Making).Suggestion: In retrospect; things that I could have done better for this event; I could have disengaged the autopilot a bit earlier on the approach (about 600 feet AGL or higher) to get a better feel for the aircraft and perhaps contributed additional cues to allow me to adjust my landing technique and improve my performance and energy management during the flare/roundout phase. Ultimately; a better picture of this approach could have helped more and perhaps aided in a go-around decision if at any point things felt slightly worst.
