Best option by what metric? For which enterprises. I say this having worked at an “enterprise” where this was not a good option. For (lack of) talent/expertise, budget, infrastructure, and actual value relative to the eventual bottom line.

Well its not the only enterprise tool, but from the perspective of llm delivering enterprise spexifc insights

Still, to get results from that you need someone who can create a decent finetune. That might not be realistic, but it very well could be realistic to have someone optimize some prompts and curate a knowledge base. Point is, its a possibility but “best” depends on the nuances of reality.
