The natural-resolution scaling of CRTs is something you just can’t do on and LCD, which has a fixed panel resolution. The free phosphor-glow “anti-aliasing” also, although that’s something that people are getting pretty good at simulating, I think.
But I wonder about the rest of it. CRTs have ~8 ms of “input lag” (basically, at 60 hz, it takes 8 ms to draw the next frame), so really, modern panels are pretty close. As I understand it, e.g. OLED has similar black levels to a CRT. So it might depend on exactly what you’re prioritizing, but you can get close in any given dimension.
Outside of extreme cases, like speed runners who do specific frame counting, and want consistency, it might not be that noticeable. (For retro-games, where they were built with some of those features in mind, and are generally much closer to the hardware, I think CRTs are clearly superior though).
