Not sure what to tell you, exactly. Don't use your power unnecessarily by leaving the lights on, don't let Foxy hit your door, and try to slow Freddy down whenever you can. The latter two are achieved by keeping the cameras up when they're trying to move. Your core strategy should involve a loop of opening the cameras, quickly looking where you need to, then closing them and peeking at each door for Chica/Bonnie.
If/When Freddy reaches the camera next to your door, you can't afford to be looking around while she could be coming in for a stuffing. The purpose of your camera is to see where Freddy is, not to check on any other gynimatronic, that's what the lights are for at this stage. If you think Freddy got into your office, hide in the camera and you might just make it to 6 AM...

You kind of gave a lot of Freddy strats, but Freddy is pretty easy since if you watch she actually has a constant loop so you can easily predict where she is and when she'll attack. The problem is Foxy. How on earth did you prevent Foxy from hitting the door? (Also sometimes getting unlucky with constant or double visits from Bonny and Chica can hurt a lot)
