jump teleport is a bad idea as stryker's uppercut punishes it clean, the gun does stop cyrax from shooting projectiles as it outspeeds him, i havent got enough experience in this matchup to really give solid advice but what i do whenever i rarely fight stryker is, once i have the life lead, sit at just outside jmup distance and neutral duck, gunshots wont touch me and grenades can be punished by a dash d4 on reaction, other than that all i can say is be wary of the roll and remember all your strings outspeed his, so if he gets in your face you shouldnt really have anything to worry about.
