Depends very much on your taste. There was an excellent series a few years ago called Hornblower, about a British naval officer in the late 18th to early 19th centuries. Lots of action, pretty clean, several examples of self-sacrafice and looking out for others. If you like comedies, you can’t beat the old BBC sitcoms. If you like science fiction, the older Star Treks (up to Voyager and for the most part Enterprise) are largely family friendly and mostly free from liberal propoganda. Babylon 5 is also a good one. BBC period dramas are also generally clean and family friendly.
With more recent shows you have more of a problem finding anything that isn’t full of both immorality and liberal messages. But in the thriller category, Bosch and Homeland are pretty good, though not sutiable for children.
