Is there anything that Adobe Camera Raw can do that Lightroom Classic cannot?

In using the select object TOO.....one needn't reselect the tool for each portion of a mask ones "building" 0r otherwise editing...as is necessary win Lightrooma

Lightrooms brush tool doesn't require re selection ...for added Steps but its object tool does.

If you have a compatible monitor and operating system, Adobe Camera Raw has had for the past year or so a High Dynamic Range Output feature preview that really shows off HDR images.  Quite a step forward but so far only available in ACR.

HDR as a Technology Preview for Adobe Camera Raw came about in April 2023:

Whatever you find in Adobe Camera Raw isn't far behind in Lightroom Classic (enough said, stay tuned).
FWIW, there are quite a few potentials 'hurt me' buttons with HDR (which is for display only) but that's another topic.
