I would have used parentheses in both places, and semicolons don't work in either one:

Sure they do. They're perfect for a related tangent without abounding the greater scope topic being discussed.

Parentheses work no question and I would argue are far more appropriate in that example since it's a minor elaboration/clarification and not a tangent, indeed, semicolons would not be appropriate for that.
In general, yes. Technical documents, research reports, news articles, and other formal publications should follow this.
Anything else which allows a bit more freedom in expression? I’d say it’s a matter of taste.
