Celeb ID?

Hi, I'm new here.  What's the best site or place to identity unidentified celebs?  Possibly right here?

For just 1 example, who is the apparently blonde singer in the following Samsung ad for their Galaxy S24 Ultra? -

And for an older example, who is the female model or actress in the following 1994 First Response (pregnancy test) commercial? -

She also appeared in some other commercials in the '90's - incl. a 1993-94 Post Banana Nut Crunch cereal commercial that also starred a very young Hayden Panettiere.

If anyone whatsoever has any idea(s) at all whom either could be, or has any potentially helpful suggestions, such as any other sites, message boards, forums, Usenet newsgroups, etc., where I could post this message as well, it'll be tremendously appreciated - THANKS very much!
