I dare to say Word is so poorly designed that there are so many ways to screw up formatting... that bad behaviors (like right aligning text with spaces) are inevitable.
For 90% of documents, software like Word was a mistake and you should be using google docs level of detail or markdown or so. And for the rest you want publishing software, not Word :(.
Hugely agree with markdown.
99% of the time people want bullet points, headers, maybe a table or two. Using a word processor is very overkill and actually makes the simple stuff more arduous.
Markdown is the best too because:
1. Sending as plaintext is so convenient and it looks pretty decent
2. Most software (gitlab, jira, etc) accept markdown input so you can just copy-paste
