When you make your own you can fudge a bit by making the landing an inch or two up or down. But the stringers should more or less be the same.

Lol, no. Do you think building floor to floor heights all over the world are being set based on a standard stair rise?
There are code minimums and maximums, but stairs will be anywhere within that range. For residential code is min. 125mm & max. 200mm for rise. Run is min. 210mm & max 355mm.
The restriction yes, is that each step must be the same throughout the whole staircase. Actually there's a small acceptable tolerance.
7" rise / 11" run is generally the most comfortable and preferable but if you have a 23 3/4" deck to grade height, what are you going to do? You're gonna be 3 rise at 7 15/16" or 4 rise at 5 15/16". Change your grade or live with either steep or shallow.
