Obviously the only solution is for Israel to reoccupy gaza like before 2006. At this stage of destruction a lot of gazans will have to evacuate as well. Of course, like you say, any other solution can't possibly work.

People can yell and moan but that is honestly the best outcome for gaza. If they are rational, the gazans are cursing the Israelis for withdrawing in 2006 and abandoning them to hamas.

The two state solution died on Oct 7.

Edit: But i've actually come up with a clever idea how everyone can (eventually) ends up a winner. It might sound desperate but remember this completely unnecessary crisis is already in its 4th generation:

A good solution that should satisfy everyone would be to offer a couple million palestinians a new life in any of the dozen arab states that exist and are much bigger then israel. They will get enough money to set themselves up and a pathway to citizenship in their adopted country. In short treating them like every other refugee in history, just much better. I've done the calculations, if 2 million palestinian get offered 50k dollars each, including children plus whatever they can get for selling their house this scheme would cost $100 billion dollars, which actually kind of makes sense seeing how much this war is costing. It might cost something in that ballpark to that to rebuild gaza anyway. You can call that whatever you want, but i'd say that is the path to an optimal outcome for all sides. (actually i like that idea so much i think it deserves the Nobel prizes in the peace and economic categories.)

Or you can get hung up about ethnic cleansing and gaza stays a hellhole for the next 20 years and increasingly overpopulated.
