This question is about the meaning of する in phrases like 偉そうにする, 幸せそうにする, and
楽しそうにする

Is this usage used to describe the way they do things/act, as opposed to doing
a specific verb such as in the cases of 美味しそうに食べる。So for example, 偉そうにする could
describe the way the person talks, walks, their body language etc. The given
example of もっと楽しそうにしたらどうなの in full was せっかくの旅行なんだからもっと楽しそうにしたらどうなの which was
said to someone who was complaining whilst they had come here to enjoy
themselves. Now from context it clearly means something like "how about
you/why don't you try to enjoy yourself more(or I'd phrase it "at least try to
enjoy yourself"), but I don't quite see grammatically which usage of する this
would come under.

Edit: Just adding some of my thoughts. Would it be like 幸せそうにする > act happily
> be happy?

The meaning of する in もっと楽しそうにしたらどうなの
In the phrases you have listed, 「する」 roughly means "to behave" or "to conduct
oneself" in a certain manner **_said from the perspective of another
person_**. The true intentions or emotions of the person in question is not
being considered here.

Thus, a definition like "to appear to be behaving" might actually be more
fitting.

To give a rather common real-life example, some of the people who get labeled
as 「えらそうにしている」 by others may indeed have no intention of acting like a big
shot. It is just that they look like they do to some people.
