> Browser support for "width: fit-content" is good but not universal (albeit requiring vendor prefixes in some cases) and for those cases where support is completely lacking one can fall back to "display: table".  However, I do not wish to abuse the "display" property in this way if it is unnecessary so to do.  Is there any standards-compliant way of falling back on "display: table" IFF "width: <possible vendor prefix>fit-content" is unsupported (as in the case of, e.g., Internet Explorer) ?

Yes.  See https://drafts.csswg.org/css-conditional/#at-supports and

             Before I built a wall I'd ask to know
             What I was walling in or walling out,
             And to whom I was like to give offense.
