Star Trek Prodigy is the true sequel to Voyager. It’s all ages / family rather than the ‘kids show’ many fans take it for. I would watch that with your GF next.

Because Prodigy is designed to be an entry point for new viewers, it introduces many of the key legacy characters and much of the lore. It has a Star Wars vibe in the pilot, mainly to draw in viewers from other franchises, but it settles into being some of the Trekiest content ever by the 6th short episode of season one.
