I hate to say it, but it does depend on weight.
For light loads below MLW you should use around 90-92% N1, depending on aircraft.
For medium loads above MLW, use 92-96% N1.
For heavy loads near MTOW, use 96-101% N1.
Also for shorter runways, higher altitudes, and higher temperatures you should increase your N1 by about 2%, depending on aircraft.
Ideally your N1 setting should be enough for you to initially climb out at V2+15 kts at 15 degrees pitch without losing speed. For prop aircraft, your pitch setting should be around 10-13 degrees. You can find aircraft charts that tell you V1/VR/V2 for your aircraft online. That’s pretty much it!
