Welcome!
Yes, as sunandshadow says, there are so many subgenres! Are you looking for historical--regency, perhaps, since you're an Austen fan? Paranormal? Contemporary? Erotic? Any combination of those?
For a regency, I highly recommend ONCE A SCOUNDREL by Candace Hern:

It's one of my favorite romances ever; witty, charming, well-written, and sexy. I also recommend any of Julia Quinn's "Bridgerton" books; I'd start with THE VISCOUNT WHO LOVED ME, because I believe that's the first. And it was my favorite. (ETA: I've been informed that in fact THE DUKE AND I is the first Bridgerton book. Thanks for telling me! You could have just posted it here!
)
For paranormals the field is so big it's hard to know what to recommend; do you like vampires? Weres? Witches? Demons?
And contemporaries...of course there's always Nora Roberts, but I confess I've never read any of her books. I did quite enjoy Anna J. Evans' SKIN DEEP*; it's a light BDSM novel with some really cool elements.

*Disclosure: Anna J. Evans is one of my critique partners. But she wouldn't be one if I didn't love her work, and frankly I don't read a lot of contemporaries; this is one I have read and enjoyed, so there you go.
I like medievals a lot but can really only think of Kinley MacGregor (a pen name of Sherrilyn Kenyon) off the top of my head; I have a hard time finding medievals I truly enjoy. (Although I did write one called BLACK DRAGON for Cerridwen Press several years ago now; my attempt at an old-school style romance.
It did get excellent reviews, which was nice.)
Hope those help!
