Is there a way to help choose a Catholic Church? I would like to join or attend a Catholic Church. Is there any way to find information about area Churches besides simply attending?
One of the oldest sites I've always relied on to find area Masses is masstimes.org.  From there you can find your parishes in your neck of the woods that you might be interested in attending.

I believe every diocese in the USA has a website and from there you can usually find parish websites.  Most parishes (who have a website) post their bulletins to their parish website, so you can get a feel for the parish without attending Mass (if there's fish fries, bingo, euchre tournaments or adoration and confession, etc...) 

Furthermore, lots of parishes can be found on https://www.parishesonline.com/ (I think this used to be called "seek and find") much of the information Masstimes.org, as well as the bulletins, can be found there too. 



It should be noted that one of the 'rules for Catholics' and I'm not sure how well it is enforced because I violate it almost every week and nobody has told me not to, is that you should attend Mass in your home parish (regardless of how much you dislike the priests's homilies) I believe this is tied to the 5th precept of the Church, which is to provide for the needs of the Church. 

In my experience "Church Shopping" isn't something that is a loved practice by Catholic priests. But in general, they want what is best for you spiritually, so if you need to go to a parish with a great community life, that's great and if you prefer a more austere parish with lots of concrete and no padded kneelers, that's probably OK too.
