The network effects of everyone being on Facebook/Twitter/Instagram are huge. You can't expect your contacts to move to your network of choice - even if they set up an account, their behaviour and the content they post will be very different. Most likely you will end up connected to a handful of inactive accounts.

What I personally do - use signal/text/email (I wouldn't bother with hosting my own email server) for 1-to-1 communication; no accounts on Facebook/Twitter/Instagram/Snapchat - they're just not worth the time and attention. Neither are Mastodon or Diaspora. I have an up-to-date LinkedIn account that I don't really use - again, worth having an account but the feed is a giant waste of time.
