Any of the standards listed should work, but some require strange crystal frequencies, or some very odd division ratios.
What seems to be most important are the frequencies. Sync pulse widths do not seem that critical, and the blanking intervals make up the active part of the display need to be fairly close.
You can fudge the blanking, and use the display height and width adjustments plus centring to avoid cropping or black edges.
But if you wish to have it display a perfect picture without tweaking, using the default monitor settings, stay as close as you can to the spec blanking intervals.
It can be a very frustrating business to get something up on the screen initially.
One other point, the video must be absolutely clean without any noise or ringing on the grounds, otherwise a plain background will look awful. Even a few millivolts of nose will be clearly visible.
Circuit board layout and a clean ground reference around the video output drivers is absolutely critical to getting clean video.
Its all jolly good fun, and a particularly interesting challenge.
