I think it would be interesting to have a series main character who's from the future, permanently living in the past.
DIS has had the reverse - characters from the 23rd century living in the 32nd for an extended period of time.
But I think it would be a new twist to have a character who's from the future who for whatever reason, can't physically return to the future (too dangerous for them as a temporal refugee, are believed dead in the future, etc). And they're not the McGuffin officer - always saving the day with magic advanced tech (though they could once or twice) They bear a heavy burden of knowledge of future tech, science, events etc that they cannot share. Yet for some reason, the timeline is only complete with their long-term presence in the past.
This character's recurring storylines could include dealing with a temporal agent handler who makes sure they don't do what they're not supposed to, and do do what they are supposed to. Perhaps they have the cover story of growing up on an isolated colony world and so they're behind the times. Maybe one episode they have to save a relative who's in danger of dying before the family line carries on.
