I started using emdashes in my academic career, after my advisor pointed me to the subtle differences. And since then, I like and use emdash a lot. In Latex, it is easily produced, just keep the spacing rules in mind. The Punctuation Guide is a nice reference on it https://www.thepunctuationguide.com/

There are actually four different "dashes" in La/TeX. The hyphen (-), en-dash (--) which is used for numeric rangen like 1--2, the em-dash (---) for punctuation, and the minus sign ($-$). Knuth talks about them in the TeXbook which is good fun.

I think you can do all of those in plain text as well. There are Unicode characters for those dashes and probably more
