Congrats on snagging that SSD! Your Asrock B450M Pro4 should work just fine with the Kingston Fury since it has the right M.2 slot for it. When it comes to transferring your files, I’ve had good luck with Macrium Reflect for cloning. Just connect the new SSD, fire up the software, and it’ll walk you through the process. I did this recently when I upgraded my setup, and it made the transition super smooth.
