100% agree with you there.
Between UI, UX, UXR, CX, SXD, IxD, HX AR/VR/MR/XRD's, etc. along with all of the internals like IA, CS, and the plethora of other titles/responsibilities thereof; I would pay EXCEPTIONALLY good money for a standardized lexicon across the industry.
A very simple "who-does-what" that is based on a standardized list of functions, which act as a standardized responsibility map for each professional under that category.
From there, we'd be able to better standardize education/training for such roles, which would make it infinitely easier to onboard and communicate across teams.
My ABSOLUTE FAVORITE though is when orgs can't quite tell the difference between a UI designer and a front-end developer, so they try to shoehorn the des into being a quasi-dev, and then get pissed off when the coded specs aren't templated/scalable in React/React Native, even though that's NEVER been part of a designer's job, and you would never expect your developer to load up Figma and start pushing pixels on the other side of the coin.
At some point, our industry needs to define and pick its lanes, or they will be defined and picked by a newer one that makes our current industry obsolete (see Midjourney and Dall-e 2 for just how close we might be to that actually happening).
