Suitable Industry and Job position

Hello, I'm new to the forum but I have been reading Bazi for some time now. Just have some questions when choosing suitable industry and job role.

Should one choose an industry based on the useful god? If the useful god is few or not found in chart, can we still consider the industry as long as it falls under the useful god element? Or does the industry matter at all? As long as one's job role is under their main profile?

When choosing a specific job position, would it matter if the element which represents their main profile is unfavorable? Or is it still okay to take on job role since one has inherent talent with it. Appreciate any advise.
