I don't read much female leads novel because most of them are romance based novels, but I know some that's action driven, some has romance while some couldn't be seen as far as I know. I don't know whether you have read them or not, so I'll just list some that I know.
It's not easy to be a man after travelling to the future

it's a story about Ling Lan, and mostly cover up about her as she cross dress as a man because of some circumstances. It's a rather mecha + cultivation story, but it's fairly fun.Genius Doctor: Black Belly Miss

It's a faceslapping theme novel with the FL often being underestimated. There's male lead and romance, but he rarely appear nor interfering in her path. Perhaps, some occasion but not too much.Rebirth of the strongest empress
https://www.webnovel.com/book/12447708905471005/Rebirth-of-the-Strongest-Empress
It's depicting the story of a reincarnated cultivator. The story mainly follow the female lead as she grow stronger. There's male lead, but so far he rarely meddled and only appear on wolf form (I hope this is not considered spoiler)
I only know these three from the translation ones. There are some others but not on this site, so I'm not listing them. As for originals one, I only know 2
Flowers Bloom from battlefield
https://www.webnovel.com/book/10580655105066605/Flowers-Bloom-from-Battlefield
It's a revenge type of story, kind of similar to Mulan story if I should say since the FL crossdress and go into war. There's male lead, but there's barely any romance and only start appear occasionally after more than half of the novel. It's complete too.Good Girl Gone Bad: queen of the underworld
https://www.webnovel.com/book/11911622506604705/Good-Girl-Gone-Bad%3A-Queen-of-the-Underworld
This is also a revenge type of story with the FL reborn in the past with her memory. There'll be a lot of actions since the FL is involved in the underworld. There's male lead too, but he only start appearing after a pretty long time and there's not much romance scene at first.
I think these five are those that I quite like in this site. Maybe there are more strong FL stories, but these are all I know so far. By the way, those description are mostly my opinion from what I have read as I'm too lazy to copy their synopsis, so it might not completely accurate.
I hope they're suitable for your taste.
