I encourage you to go take a look at the larger 501(c)3 non-profit "aka. charities" in your area. Here's a few from San Antonio where I live:

Haven for Hope (transformational campus to combat homelessness) https://www.havenforhope.org/

San Antonio Food Bank (part of a national network of food banks) https://safoodbank.org/

Catholic Charities, Archdiocese of San Antonio (I'm the Board Chair, we run ~40 programs meeting people where they are and helping them on a path to self sufficiency) https://ccaosa.org/
