Woma in Chinese / Japanese...

美麗的女人 is the best and most polite way to express “beautiful woman” in Chinese.

Note: Some people may like the simple 2-character 美女 way to express this, but there are some bad connotations with that, so better to stay with this longer and more respectful title.

沈魚落雁 is an old proverb that literally means “fish sink, goose alights.”

...But this takes some explaining. This is a proverb from Zhuangzi (莊子), who lived in the late 4th century BC.

This figuratively refers to female beauty that is so captivating that even the birds and beasts take notice.

Perhaps a better and more accurate way to describe this is to say that it speaks of the charms of a uniquely beautiful woman who is so beautiful that fish stay on the bottom of the water and flying wild geese fall from the sky in shame.

This proverb is so famous that it is also known and used in Japan (same characters, different pronunciation).

Note: This can also be written 沉魚落雁 instead of 沈魚落雁 (just the first character varies slightly).

玄人 literally means “Mysterious Person/Woman.”

In Japanese, this is associated with a “geisha,” which matches this definition of a “mysterious woman.” However, this is the colloquial way to say “professional geisha” or “expert prostitute” in Japanese. It, therefore, might not be what you want on your wall.

Notes: This is a "Japanese only" term, though a Chinese person who sees these characters will think of a geisha or an alluring Japanese female musician.
While not often seen in Korean Hanja, this would mean a "dark woman," as in a woman that you cannot easily see through.

This can be read as “girl power,” “woman power,” “women empowerment” or “female strength.”

女力 is kind of a strange or unofficial title in Chinese and Japanese. At least, it's not common for a wall scroll.

This should be “onna ryoku” in Japanese but I found some who suggest it should be “me riki.”

女傑 can mean brave woman, heroine, lady of character, distinguished woman, outstanding woman, and sometimes prominent woman.

Some people might use this to give a title to women like Amelia Earhart, Rosa Parks, Queen Elizabeth the First, Joan of Arc, Mulan Fa, Yevdokiya Nikolayevna Zavaliy, Harriet Tubman, Anne Frank, Clara Barton, and Jane Eyre.

I use it for a woman like Araceli Segarra (the first woman from Spain to climb Mt. Everest) and gave one of my daughters the middle name of Araceli.

女強人 is the best way to say “strong woman” or “strong and independent woman” in Chinese.

Grammar in China is a bit different, so these three characters literally read as “female strength person” or “woman strong person.” This might sound funny in English, but this is a natural-sounding title in Chinese.

烈婦 is a Japanese title for a strong-minded woman, virtuous woman, or heroin.

In some contexts, it can refer to a pure or chaste woman.

淑女 is an ancient title for a wise and virtuous woman or lady

In Japan, this can be a female given name, Kiyome.

賢女 is a Japanese title for a wise woman or clever lady.

巾幗 is the very old way to say woman in Chinese.

A common title in ancient China, this actually refers to the scarf or head wrapping worn by virtually all women at that time.

巾幗 is kind of a cool way to say Woman now. The actual gender character alone on a wall scroll would actually look like a fancy sign for the woman's restroom (WC).
If you are curious, the character to the right means female or woman. Knowing 女 is useful information if you are a woman searching for a toilet in China or Japan.

巾幗英雄 is an excellent and somewhat ancient way to say woman hero in Chinese. 巾幗英雄 is used in modern times to refer to an outstanding woman or a woman with significant accomplishments.

In the old days, it was a title for a woman warrior (oh, did I mention that there were great female generals who led massive armies into battle in ancient China?)

婦人會 is a Japanese title for women's group or association.
