The (voice) actors were too... and they were well versed in the lore. Tawny Newsome (Beckett Mariner) became a writer for Star Trek: Starfleet Academy ( https://en.wikipedia.org/wiki/Star_Trek:_Starfleet_Academy#S... )
Wil Wheaton in Ready Room has some episodes about Lower Decks. The Crossover episode https://youtu.be/3SiYyIAz5xU and the final recap https://youtu.be/NK94dXm2Wis
I'd also generally suggest Dropping Names with Brent and Jonny ( https://www.youtube.com/@Dropping-Names ) where Brent Spinner and Johnathan Frakes chat with people about movies and TV. While it's not about Trek, it's a frequent tangential topic. I believe it's helpful in the context of "how much the fandom extends to other people in the entertainment industry."
