I think lack of planning is part of the reason the Kelvinverse films have burned out so quickly.
I look at the recent Planet of the Apes trilogy for an example of how these ST films should have been handled. The POTA movies are all part of a large connected story (as opposed to the one-off villain movies of ST). They have nice special FX and action, but are mostly character focused. The action doesn't feel excessive and over the top like the Kelvinverse films. There's lots of quiet moments in these movies and the filmmakers aren't preoccupied with stuffing in references to the franchise's past. Each film in the trilogy was released on schedule once every 3 years with simple straightforward honest marketing.
Didn't War for the Planet of the Apes badly under-perform, much like Star Trek Beyond?

War for the Planet of the Apes was disappointing ($360m+ on a $150m budget), but Fox can merely choose to close the franchise on this natural end.
