A Unitarian system might be better, faculty run classes maybe without even TAs, your grade is however you do on your final, Spartan campuses without student amenities. The kids would be more depended on themselves to sink or flourish, but it’s almost like that anyways.
But if I had to choose for my own kid and had the money to afford it, I would still go with the full campus experience, although a Unitarian experience would probably be better for access overall.
The unitarian model you mentioned is the norm in Germany and France (and even the UK to a certain extent - a CSU will have better student amenities than Oxbridge tbh).
