word choice
The specific selection of words that someone uses when speaking or writing.
Der Redner überzeugte durch seine klare und präzise Wortwahl.
The speaker convinced the audience with his clear and precise word choice.

This word is made up of 'Wort' (word) and 'Wahl' (choice). So it literally describes the 'choice of words' that a person makes.
Eine bewusste Wortwahl kann Missverständnisse vermeiden.
Careful word choice can prevent misunderstandings.
'Wortwahl' (word choice) is often evaluated with adjectives. Typical combinations are 'eine gute/schlechte Wortwahl' (good/bad word choice), 'eine unglückliche Wortwahl' (an unfortunate choice of words), or 'eine gewählte Wortwahl' (a refined choice of words).
Seine unglückliche Wortwahl führte zu einem Streit.
His unfortunate choice of words led to an argument.
A very common expression is 'auf seine Wortwahl achten' (to watch one's choice of words). This means that you should think carefully about which words you use.
In einem Bewerbungsgespräch solltest du besonders auf deine Wortwahl achten.
In a job interview, you should pay special attention to your choice of words.
style
'Stil' and 'Wortwahl' are closely connected when it comes to speaking or writing. 'Wortwahl' specifically means the words someone uses. 'Stil' is broader: it also includes sentence structure, tone, structure, and sometimes personal effect. The words can be confused because word choice strongly influences style. If only individual words are appropriate or inappropriate, you would more likely say 'Wortwahl'. If it is about the overall impression of a text or conversation, you would more likely say 'Stil'.

Bei der Entschuldigung war seine Wortwahl sehr vorsichtig.
In the apology, his word choice was very careful.
Ihr Stil wirkt freundlich, weil sie ruhig und klar schreibt.
Her style comes across as friendly because she writes calmly and clearly.
