Nice to see this discussion being bumped (and trending!) because we can’t have enough female-led titles and my hope is more comics are added for us to read, including more Wonder Woman!
Batwoman had a 40 issue run starting in 2011, and then starting in 2016 she had a second run of 18 issues. I would also recommend all eleven issues of CHANCE, about an agent who can’t stand metahumans because of spoilerly reasons. There is also Manhunter (38 issues) that I like quite a lot. Anything Wonder Woman written by Greg Rucka is highly recommended.
Bombshells and Black Canary are solid titles. Death doesn’t have a lot of solo books, but those are good. Cinderella was awesome, and tied to Fables. Fables in general has great female characters, though probably not as focused as you are looking for.
There’s also Huntress, Zatanna, Madame Xanadu, Mera (the recent limited series), and of course Black Canary – whose original run of solo stories began way back in 1948’s Flash Comics #92.
