What will it be like to live on Mars? Inflatable and super sustainable

I’m skeptical of what radiation shielding can be fashioned into an inflatable structure. I suppose it will be similar to the shielding used in current spacesuits and on the ISS. The thing is, though, that Martian travelers will be exposed to cosmic/solar radiation for much longer durations than the ISS personnel, whose missions are generally of the 6-8 month duration.
I expect that permanent habitats for years-long missions or for those that go to stay will be constructed underground.
