1: Do I use “aspect(s)" correctly?
2: Should I say “aspect or aspects”
I am interested in the technical aspect / aspects of accounting work in the business field, for example, financial analysis.
I am interested in the non-technical aspect / aspects of accounting work in the business field, for example, advising clients on their financial strength.
I am not sure whether people treat each technical area separately or not.
If not, “aspect” should be used.
Since the sentences provide examples, "aspect" should be plural.
The technical aspect of something refers to all technical aspects as opposed to the non-technical aspects.
