Off the top of my head, not sure what your general budget is:
Chanukah is coming up. This may be done already, but you can contact your community’s Tomchei Shabbos and add something extra for one week or a game or gift certificate to a toy store. The gift certificate will give the kids a chance to have the fun of choosing and get something they definitely like and it may be the only presents they get. Even if its something small to several families.
Some organizations are emotional support based (divorced parents, families with special needs children etc.) rather than straight out Tzedaka. You can ask if they would be interested in a “fun night” with a comedian or another activity that may be within your budget (or a portion of it) and its a chance to bring a smile to some people’s lives.
I think Oorah (and I’m sure other organizations have as well) have an option do donate specifically for a certain purpose. Something like buying Siddurim or another item used for a Mitzvah is not only Tzedaka, but also a Zchus for the Niftar when the item is used. You can do this in a local Shul as well whose Siddurim/Chumashim can use updating.
May the Neshama have an aliyah.
