I would not worry about being a people-person. Just start discerning your vocation and that will sort itself out. If you are meant to have a Religious vocation, God will lead you to it (not that it will be easy). If you are not enough of a people-person or scholar-person, or prayer-person, or hard-work-person, or whatever the charism of the community requires, they will delete you faster than clicking the X on the toolbar.
What I am saying is: a community will decide for you whether you belong there. Talk to your priest. Talk to the vocations office of your diocese. Don’t state your non-people-person case. Just start the process and see where the Lord takes you.
I have found that even hermits, who are called lengthy periods of silence and solitude, are delightfully people-friendly. Different people have different thresholds of happy interaction. I suppose a hermit would be miserable in a college fraternity.
