Here is a list of the California peaks over 14,000 feet:https://www.summitpost.org/california-14ers/170899
Of course none of them have a hiker trail to the summit, but the Summitpost.org list show the easiest way up all of them. And...there is no long frustrating permit waiting list with "annoying" and "incompetent" government employees involved in the permit system.
Here is a challenge to potential first-timers to Mt. Whitney: would any of you consider an alternative to Mt. Whitney. If not, why not?
Another question to those who have summited Mt. Whitney: were any of you just a wee bit disappointed in the fact that the West side of side mountain is not very visually attractive?
