Hello OhioNewbie. While NJbob has some good recommendations I found that Goat's Beard is super invasive, my patch went wild and it took years to eradicate it from the garden when I didn't want it spreading everywhere. Some of the natives are nice but hard to find and hard to get started without about perfect woodland conditions. Hosta's do well in shade, Celandine Poppys do well in my shady woods and I'm in Indiana so we're the same Zone. Annuals like impatiens add color and are inexpensive to find during the spring garden sales.
Just some options to consider.
