If you don't care about open source and don't mind spending money, Izotope RX7 has much better denoising tools than Audacity. It's actually the main reason I now have Windows installed on my desktop (alongside Ubuntu).
I know a lot of things about audacity can be a bit clunky, but the quality of the denoise tool in Audacity is actually extremely good. I read its code one time, and I was impressed.
I'm not familiar with RX7, maybe it does better audio quality but it's probably also got a better interface/workflow. Which is definitely worth a lot in a professional setting.
