I mean, there still aren't that many Intrepid-class ships (or even California-class, for that matter), compared to the population to draw staff from. Comparing them unfavorably to the flagship is quibbling about slightly different positions that are all still way off the top end of the bell curve.
The Orville, maybe? One of the plot points in the first episode was how the Federa—sorry, "Planetary Union" had so many thousands of ships they were having trouble finding qualified captains for them all.
(That's in direct contrast to how Star Trek does it, as I pointed out in my other comment. Neither setting really gives hard numbers, but the vibe is that Star Trek has way fewer ships per capita.)
