I have read a little about psychiatric wards, and I have known people who have been to them for temporary stays. I think the best way to run them would to make them a middle ground between the two types you described. I wouldn't want any of them to be cushy vacation spots with internet. I think internet should be banned inside them. From the people I know who have had temporary stays due to suicide attempts, they said that they were not allowed any electronics, and it was either a boring environment or an eye-opening environment being yelled at by schizos. They did not have any desire to stay in the ward, but they also did not feel absolutely tortured. I think making it a place you don't want to go, but also not unbearable torture either, is a good way for patients to have motivation to get better to want to get out, which maybe that's what they're going for? Patients won't feel like they're being sent to the gulag, but they also will still miss real-world luxuries like the internet.
Internet detoxes in general tend to be good for those that are addicted to it. But if they're convinced the internet is the only place they're "accepted" (since they're Nonbinary Asexual Sapioromantic Polyamorous or whatever), that can be hard to detach from. So maybe they need to be forced to have time away from it in a ward.
Edit: Providing practical education or trades work training in them would also be good, since it's something they can continue once they're out of ward treatment. And if it's one of the few limited activities in the ward they can do, then they'll naturally be more inclined toward it. Cushy vacation wards with internet won't be effective in changing anything about the patient because they'll just continue their same behaviors.
