There are a lot of people around here who are Oblates, Third Orders, etc. If there is an order that’s a good fit for you spiritually there are a lot of benefits. I’m a Benedictine Oblate and that’s an important part of my life.
If you’re mainly looking for something where you could meet people and share your faith, then you may do better to look at something in your parish or geographic area.
Within my parish there are all kinds of groups that focus on different kinds of activities. I belong to a small faith community that meets weekly and that is hugely important to me and enriches me spiritually (as well as forming deep friendships). I’m also an RCIA catechist and that enriches me in a different sort of way. Depending on your interests perhaps something that’s more social justice oriented would be of interest.
If you feel called to join a Third Order or something similar, then you should definitely pursue it. But I also see advantages to doing something with fellow parishioners.
