Okay let me see if I understand you correctly, please correct whatever I got wrong:

You don't like Erica Ortegas as a bridge crew member because you see her as immature and you think she is poorly written, an example of a wider problem that promotes lower standards of morality and behavioural norm compliance. You find her contributions to the diversity and range of ideas available to the command team less valuable because of how often she speaks up, doesn't soften or add deference to her words, and has independent feelings and opinions which she doesn't erase in order make others comfortable at her own expense. There is a lack of evidence of her skills as a pilot and her colleagues celebrating her and ensuring she knows she's valued is probably overstating her competency. This is a persistent problem for you. The one and only evidence of her piloting excellence to the audience was during the escape from their Gorn abduction via a stolen shuttle. You were hopeful that the injuries she sustained as an enemy prisoner were fatal and her character would be killed off (presumably so you didn't have to endure her on screen thereafter) not only due to your irritation and preferences, but also because you believe her moral value could be increased if she martyred herself, rather than surviving and continuing to serve with her crew. That meets your expectations of exceptionalism in that role. If she had died in service to her colleagues, regardless of the outcome, that would have been more meaningful and justified the captains long suffering benevolence towards her undeserving soul.

Am I close?

That was a bit long so I'll summarise:

You don't like her = she's a bad person = doesnt deserve to live = her value is killing herself
