I'm sure this topic will go well.
I don't think I've received a business card (except from a detective with a case number for an insurance claim after a car break in) in the last five years, getting handed one at this point instead of an email, linkedin message, or similar would surprise me way more than pronouns.
On the pronouns thing, I don't do it but reading an extra three words in an email signature, resume, or whatever doesn't hurt me at all, and I can think of a case or two where it would've helped me to know how someone wanted to be addressed. I just make a note of any time there's a discrepancy from what I would've guessed and move on with my day. If that's the most annoying thing I run into in my work day, I'm having the best day of work that's existed and life is good.
