@helmut_meukelClichés are also "common knowledge" while they may be over used, deliberately going against them, without addressing the "aberration" is also a mistake.
Using a previous example, if a character is described as having red hair and green eyes, and a last name of Murphy, most English speaking audiences will accept that; more detail isn't necessary, because many people will "fill in the details" for themselves.
If a character is described as having red hair, green eyes, and the last name of Ohara, and of Japanese ancestry; the audience will expect, if not an explanation, at least it being addressed in the story.
Clichés can be a useful tool, letting the audience imagine a part of a story you don't need to detail. If the MC needs a lawyer, but your story focuses upon other matters, but failing to mention the MC has legal representation would likely result in questions or disbelief of readers. You could name the lawyer Mary Smith, never give her a line of dialog, and the lawyer is a non-entity. That might be okay, but a bland world is often boring. If the lawyer's name is Saul Greenberg, sure a Jewish lawyer is Cliché, but with no more description than Mary Smith, many readers will make up their own perceptions of Saul. From the lawyer in the show Better Call Saul, to an overachiever, top of his class at Harvard Law, a conniving shyster, or a "bleeding heart" do-gooder, among common tropes.
If all of the lawyers in a story are Jewish, that might be plausible, but That would be Cliché. Instead, if you introduced a group of lawyers as Saul Greenberg, Michael Stein, Miram Weiss, Henry Wong, and Darius M'Tumbo, you wouldn't necessarily have to detail any of them. Several fit the trope, but the writer has included "diversity" just with the names (even if they all share nearly identical perspectives, and backgrounds) [readers are likely to imagine a variety of backgrounds to those minor characters, or ignore them].
If you have a scene: My court appointed lawyer walked in, she didn't have a briefcase, instead she yanked a portfolio out of a messenger bag; mostly I noticed her pink hair and multiple piercings...
Your readers will expect you to "pay that off" not assuming you are just avoiding clichés.
