As anon so helpfully pointed out the beam doesn't actually have a horizontal resolution beyond the theoretical speed/timing limit which I'm sure is astronomical. The CRT's surface does though so if you want to get autistic about it the best image would be one with a horizontal resolution that matches the physical pixel density of your tube or a multiple thereof. Actually I guess it might even be theoretically possible to make a 3x horizontal resolution filter that separates the color channels and actually aims to hit the individual slots in the grille but that's pretty crazy.

The NTSC standard is 720 horizontal but definitely not every TV was manufactured to physically have that resolution. I just snapped pic related of one of my cute little 5" consumer sets for example of one that clearly falls short of even the NES's 256x240. Advertising "700 horizontal lines" was saying that you would actually get to see the whole image when watching broadcast TV (minus the 10 lines of overscan on each side).

As an "interesting" aside, we can see that since the NES's resolution isn't an even factor of 700 or 720, when displayed on a typical consumer CRT it would have either had half-pixels all over the place or (more often) significant overscan. That's why the battle for the "correct" way to display game consoles will never end, the "developers' intention" actually didn't exist.
