Beyond Selidor

Crown of Stars is indeed one of hers — an epic fantasy series inspired by early medieval European history. Cold Magic is a fantasy trilogy set in an alternative version of Europe in which the Ice Age never ended, there are sentient dinosaurs, Britain is connected to continental Europe by land, and is (due to various migrations) ruled by an African-Celtic magic-using dynasty. I've heard some people found the central romance offputting (it's an arranged marriage, it's deliberately echoing Pride and Prejudice in terms of how the characters react to each other), so that may have been what made you stop.

I'm not keen to push authors/works of media on people if they've given them a try and disliked them for some reason (there's nothing more annoying than someone being pushily persistent about their favourite book/movie/etc if the other person has made it clear that it didn't work for them), so I'm somewhat hesitant to make any further recommendations! But possibly it might be better to start with Court of Fives. This is a YA trilogy, inspired by Little Women, set in a fantasy version of Ptolemaic Egypt, and it's ultimately about a revolution against colonisation, with the revolution led by women. The thing with Elliott is her books take a while to get going — I always find the first two thirds are detailed worldbuilding and character work, and then suddenly everything happens with great intensity in the final third — so starting with a shorter YA book is less of an investment in terms of time and effort, if you're trying to figure out what works for you.

But, as I say, my very very favourite is the Crossroads trilogy. Other people always rave about the fact that it has giant flying eagles with riders who are kind of bonded to them, but my favourite thing about the book is that it basically interrogates the old fantasy trope of 'dispossessed chosen ruler claims a throne and solves an entire kingdom's problems' in an incredibly clever way, and its heroine is heroic because she learnt bargaining and diplomacy from being a market stallholder in the equivalent of a medieval Silk Road town, and applies those skills on a grander scale. However, I don't think it's the right thing to start with if you're giving Elliott a try because it's very very long!
