I would still argue that from everything you mentioned, using Windows is the only acceptable thing if someone has no knowledge of Linux distros. And in most cases, the average Joe won't have any. Everything else you said, is not recommended.
But I, on the other hand, would argue that using Windows is absolutely not acceptable, that Windows is insecure, that Windows is spyware, that Windows has enormous amounts of unnecessary and non-removable bloatware filled with God-knows-what code, and so on. To me, none of the things I mentioned are acceptable. To you, using Windows is acceptable. To someone else, turning off rather than removing connectivity hardware might be acceptable. And so enters the gray area of what constitutes an airgapped wallet. Either commit to doing it all and doing it properly, or opt for a hardware wallet.
It's like the old saying - Good, Cheap, Fast, pick two. In this case we would replace fast with easy. Hardware wallets are good and easy, but not cheap. Airgapped cold storage (provided you have a spare device you can use) are good and cheap, but not easy. Mobile wallets, web wallets, etc. are cheap and easy, but are not good.
