I don’t generally use social media.
If you’re in the Fediverse, you can connect to me at @firstname.lastname@example.org, or for those who like to observe from a distance, it’s https://social.thecrow.uk. Be warned - it’s mainly just me talking to myself or shouting into the void.
From time to time, the void shouts back.
Otherwise, email is your best option. email@example.com
What? You expected my phone number?
