Yes, more or less. That is ESR/ripple vs size vs capacitance vs voltage.

Well, eventually comes down to size.

Same size will have lower capacitance vs higher voltage dependency, and the ripple rating either stays the same or goes down if you keep the same case size but increase the voltage. Most times, especially if the increase in voltage is several times, it will go down.

So you have to increase the size quite a bit since you want the same capacitance and not lose your ripple rating. In old radios we are not limited with the space.
In any other applications we are.

Also in commercial consumer application the significant difference in price between even 16V and 50V caps of the same capacitance and ripple rating will simply kill you.
