FWIW, I haven’t consulted the literature on this, but if you’re interested, I noted my personal experience with some of these treatments here.
Judging from my PCP’s positive reaction to my sharing I was using these approaches and my subjective experience with them, they are safe and effective. (My PCP also suggested phenylephrine, which is the more readily available but weaker variant of Sudafed, to alleviate nasal congestion, but after the steaming I didn’t feel a need for it.)
