Yep, good points.

Indeed, during decision-making time, the people signing the checks always think that everything will fit nicely.

With customizable ERPs, what I have witnessed all my career were companies refusing to change their (universally hated, bureaucratic, insecure and inefficient) internal processes and having to pay more for customization.

The problem in the end is that there is rarely any shift, unless you have major cultural shift and oversight, coming from someone with the intention to save money and custom development time.

Inertia always wins.
