Alfre Woodard appeared in Luke Cage as Mariah Dillard four months after playing a small role as a different character in Civil War, for whatever that indicates. Which might just be that Marvel doesn't worry overly much about reusing actors.
However, according to the link posted above, Charlie Cox as Daredevil in Spider-Man 3 is just a rumor, and one that Cox denied the last time that somebody asked him, so let's not get too worked up until there's official confirmation.
I'd like it if the Marvel films were acknowledging Marvel tv shows as canon, much like how I'd have liked it if Star Wars movies acknowledged Star Wars novels as canon, but I never got my wish then so I'm not going to worry overly much about it now.
