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."

As one would hope, given that it shared the same time setting and some characters. It's truly a shame they never managed to get Patrick Stewart in for a guest appearance.
