That would be my recommendation. Unfortunately I get hooked by pilots and first series that appear to be good TV, with a promising hook. But nowadays I don't start watching a series - even the pilot - until Wikipedia tells me that the show has a successful conclusion.
Every now and then I'd tune into an episode of The X Files and it was universally grim. To be honest, the Outer Limits (1960's version) was more effective as a show in a similar genre. But my husband, who is in all other respects, a wonderful human being, just doesn't like SciFi or shows that tend toward the supernatural, so our prime time viewing is more limited, and I tend to watch this stuff alone, mostly late at night. I never found any of the shows in your list especially compelling. The Expanse was much more effective at introducing unexplained, or not well understood, odd remnants from a more advanced but defunct culture, but even those guys were at a loss as to how to end the books effectively. They were well written and the series very good, but they decided to yank the plug without really finishing the books. I guess it wasn't that much of a loss, but it was so well done that I was sad that it ended.
