I think CP77 would only win if were NOT open-world adventure, but rather like Deus Ex: Mankind Divided or the original Mafia.
Story missions, and in-between — limited, pre-written activities, side-jobs included.
For example, after the Heist V must go undercover, because Arasaka ninjas are searching him to take back the Relic etc. So V must hide in one small area at time, where local fixer hide V in return for some jobs completion. Main plot is developing, and V moves to new areas to hide, because, for example, previous area is compromised and local fixer can'r protect him anymore.
Each and every gig and job have reason — work for local fixer in return for his protection. Each location has a major NPC like Panam, River, Judy or Kerry, whom V can help or not. I would probably add some game mechanic of V's cover — hitting the citizens with your car, open firefights and other noize would decrease your Cover meter, and if it's zero, game over. And some jobs and gigs could also decrease or increase V's Cover meter.
That approach would allow devs to reroute their time and effort from open-worldness (which they failed) towards plot, characters and sidequests.
