String theory in all it's permutations is still fundamentally untestable and had been since it's inception. I can't speak for academia (though I did watch a YouTube video that claimed to, and it ended up with this same conclusion, fwtw) but in scientific media string theory is more or less absent now. Early 2000s it was everywhere but the standard model kept plugging along without string theory, and now I only see it if I look for it specifically. It's not the leading train of thought and I doubt it ever really was - it was just popular in media. The standard model for quantum stuff and special relativity/general relativity for macro stuff is still the generally accepted view
If your view of string theory is through the lens of media, you aren't going to be up-to-date. String theory was and is the leading theory for quantum gravity, is actively worked on, and has only been supported in recent findings through quantum field theory.
But you're talking about a field with little funding, that requires some of the most brilliant mathematical minds who have specializations, and in which experimentation requires super technology to build particle accelerators the size of the moon. It's not a glamorous field and once the buzz of "theory of everything" wording died off, it was forgotten in media. Just like so many other topics before it.
The standard model doesn't handle quantum gravity, which is kind of important. Nor does it address a slew of other very real phenomenon (dark matter, for instance). It's not a theory of everything, just a good model. It's also something that can be derived from string theory. The two are not competing ideas.
