Why do the majority of games aim to run at either 30 or 60 frames per second? Is there any reason those two numbers are most commonly chosen? Why not aim for 40 or 50?

Most older TV’s in North America and Japan had a refresh rate of 29.97 Hz. That’s basically 30 Hz. You wanted your game console to produce a new frame every time the screen refreshed to keep up with it.
As TV’s got more advanced and digital, a lot of them went up to 60 Hz refresh rate. Again, that becomes a target for game consoles.
As for why these numbers, the North American and Japanese power grids operate at 60 Hz. Older devices could use the frequency of the electrical grid as its timing clock, rather than having to implement their own clock. The 29.97Hz was originally 30 Hz but had to be slightly adapted for Colour TV.
