I would bet they are quite similar. I can't recall if there are any modules in the center seat of the bench that obviously aren't there in the buckets, but the seat heaters etc. should all be the same. You may need to swap out trim pieces as well since the tracks are likely different. However, remember that the seatbelts have pretensioners, so be really careful if you're working with those, especially in the 2019's with the inadvertent firing we're seeing on some of those. I would definitely do the work with the vehicle completely discharged, but I haven't looked to see if you can remove the seats without removing the belts. Regardless, if the bench is intact, I would grab it and all the parts around it, so you can start surveying everything.
