Rec for an isekai into noble fam, brings tech with.

I'm looking for some recommendations for a manhwa where a female protagonist is isekai'd into the body of an aristocrat/noblewoman, becomes an entrepreneur of some kind and becomes wealthy and powerful from introducing items from our world/their first world to sell to a much less technologically developed society.

Some examples of titled I've read/'m reading:
      - I'll Be The Matriarch In This Life
      - I Didn't Mean To Make Him Obsessed
      - Marriage Of Convenience (kinda, with the lace and candles...)
      - Villainous Princess Wants To Live In A Gingerbread (Cookie) House
      - Isn't Being A Wicked Woman Much Better?

Etc...

I am reading others, these were just the most relevant that came to mind.

I really really LOVE when characters think they're doomed and they use their unique knowledge and intelligence to her themselves or of their situations.

Thanks in advance!
