At normal SMPSU speeds all the rise times and so on are not normally a problem with MOSFETS.
The important bit is the on resistance and the maximum voltage and package style if you already have the heat sink.
I have an 800 volt one running at 30 volts on the robot that guards my workshop kitchen garden against unwanted digging by visiting animals. They make a hasty departure before any damage and after several meetings with the robot they become reprogrammed to keep off.
They soldier on for ever with an easy job like that.
