I don’t think Star Wars story ran its course unless it’s just the Saga of Darth Vader 1-6. We never got Luke’s story post episode VI on film. I mean I guess you could claim the Saga was complete with Return of the Jedi. from a certain point of view. The Disney trilogy is the end of his journey, and it was only beginning in episode 6.
Star Trek by its episodic nature could go on forever. You can never have enough Kirk and Spock and The USS Enterprise.
And as for Marvel I’ve waited forever for an X-men film. All I wanted out of Marvel was a good X-Men film, and maybe a Fantastic four and then I was fine with being done with it. I’m not a fan of Disney Marvel I’m a fan of the comics.
The only other thing would have been a Raimi Spider-Man 4 with Tobey that was not a realistic thing to want. Sony and Marvel’s partnership and all that being what it is. I don’t at all care for the new Spider-Man movies except for that last one. But the nostalgia and multiverse stuff is getting stale.
Star Trek post Kurtzman is going to be a hard road for whoever takes the reigns. They can continue to do reboots and nostalgia and prequels or they can do something new, move the timeline beyond Picard season 3 and do a show in the 25th century.
Same for Disney Star Wars they have to move beyond the sequel trilogy timeline. They have to own The character of Rey Skywalker and the future of their own intellectual property.
