First weight. Then resolution. I think SoTA for CRTs peaked at early HD resolution 720. One might be able to modulate the beam faster now. Size. And safety - anyone starting up production now would have to solve the safety issues from scratch. Nothing like a few cubic feet of vacuum imploding to ruin your day.
Resolutions were very high for the time, I have a 2002 LG f900p (pretty high end, yes but it wasn't super expensive even back in the day) running at 1920*1200@85hz and it's a delight to work and play on it.
IMO, the only factor that kills the crt vs a moderm monitor is the size and weight. I imagine resolution would be limited by how small the dot pitch can actually be made to be with modern processes but with the advances in magnets and power electronics devices I imagine going at MHz horizontal frequency would be not that hard.
