I think “What is the purpose of this meeting and why am I being included” is almost polite as-is, but “why am I being included” sounds a little rude. Maybe “what is the purpose of this meeting and is my presence needed?” Maybe “beneficial” instead of “needed” depending on who exactly you’re emailing.
If you ask the person who invited you to a meeting “is my presence beneficial” they’re going to answer “yes”. That’s why they invited you.
The purpose is to figure out whether your presence is actually needed, not whether they think it is.
I do like a lot of your ideas though, I might suggest:
“What is this meeting about? I’m trying to figure out if my presence would be beneficial.”
That way you are the determinant of whether your presence is necessary, and the other person has to articulate what the actual benefit would be as opposed to just saying “yes”.
