CRJ-700 First Officer reported receiving a STALL FAIL message along with L and R FADEC FAULT 2 Status messages. The flight crew ran the QRC and QRH procedures and determined that continuing to the destination airport was the best option. They coordinated with ATC to land on the longer runway; but reportedly forgot to alert the flight attendants of the situation before landing.

Narrative

Immediately after liftoff I was alerted by a single chime. I observed that the Stall fail caution message; the L FADEC fault 2 status message; and the R FADEC fault 2 status message were all displayed. I kept the flight controls; took the radios; and directed for the QRC followed by the QRH for the stall fail caution message. As directed by the QRH; we selected to First Officer's STALL PTCT PUSHER switch to OFF. We then computed our adjusted Vref and increased landing distances as directed. We determined that it was safe to continue to ZZZ but I decided that I wanted to use [Runway] XXL instead of XXR because it was significantly longer. we informed Dispatch and Maintenance of the situation and continued to ZZZ. We coordinated our requested runway with Center who relayed the request to ZZZ. After explaining that the QRH directs us to come in faster than normal (QRH says add 10 kts. minimum; I elected to set Vref at the adjusted calculated speed of 138 and stayed between 148 and 138 during the approach and landing) and would be landing longer than normal; ATC told us we could expect Runway XXL. However; ZZZ Final Approach told us that we would have to land on Runway XXR unless we were [requesting priority handling]. I elected to [request priority handling]; we received clearance to land on XXL; and I did so. We [requested priority handling] a very short time before we landed. On the rollout on XXL I realized that I had forgotten to inform the Flight Attendants of the situation or go over the briefing items.For my part; we had not briefed or set up for XXR so taking the last minute change of runways was not a reasonable option. When told I couldn't have XXL without [requesting priority handling]; I should have asked for delayed vectors to give myself some more time to think things through and do them properly. I should have used the time to either go over the briefing items with the Flight Attendants if I chose to [request priority handling]; or properly set up and brief the approach into XXR and ask ATC to either let us land on the runway we are told to expect or to inform us much earlier that the longer runway is not available so that the decision of weather to take the shorter runway or [request priority handling] isn't delayed until the last minute.Even though our landing distance calculations told us that XXR was legal; I was especially cautious because I had less than 20 hours of PIC (Pilot in Command) during the event. I remembered an example from training of an aircraft that came in fast into ZZZ1; landed long; floated; and just barely stopped in time to stay on the runway. I was concerned and wanted the extra runway in case I was slightly high on short final and my lack of experience caused me to misjudge the amount of additional extra runway that might require. We ended up exiting on [Taxiway] XX after an uneventful landing and had we landed on XXR we would have been just fine and likely exited on [Taxiway] XY. I failed to notify the Flight Attendants because the thought that I needed to simply didn't enter my head until after we landed. I should develop more experience so that these kinds of situations do not cause me to feel task saturated and consequently miss important things.
