I've dealt with indoor flooding in the past and was recommended Decon 30[1] by an experienced remediator. Its main active ingredient is thymol (from thyme) and it's EPA approved for fungicidal, bactericidal, and viricidal use. Pretty easy to find on Amazon or at a janitorial supply store. Safety data sheet here[2].

I found it generally more pleasant and less harsh on the skin in particular than hydrogen peroxide or cleaners from Clorox.
