I think you've hit on some interesting points here.

Apple's customers can be roughly divided into 2 groups: public and professional. Professionals want a machine to get work done whereas the public just want something that works.

You would assume that Apple would then label its products accordingly, for example a member of the public would buy a regular Macbook and a professional would buy a 'Pro' model.

Apple however doesn't work like this at all! Every Macbook, even the base M1 Air is capable of a lot of tasks without breaking a sweat. This is in contrast to their 'Pro' iPhones which don't really offer any features the regular iPhone doesn't; they only really serve as an upsell with a few 'nice to haves'.

Which brings us nicely to the iPad Pro: its not really meant for professionals. Thats not to say it can't be used for work. A chunk of my own job requires LiDAR scanning, Photogrammetry, 3D CAD, Zoom meetings, technical drawing and photography and I find the iPad Pro to be capable in all these areas.

But something Apple won't tell you is that for everything bar the LiDAR and Photogrammetry (due to hardware limitations) I found my old base-level iPad to be just as good. It even did the 3D CAD (via Shapr3D) without any problems.

The iPad Pro is much like the 'Pro' iPhones and contains some 'nice-to-haves' like ProMotion and more RAM but nothing to really make it better in real terms because it is unlikely you are editing 3 feeds of 4K video simultaneously on it or attempting to render textures onto a complex CAD model.
