Don't delete the accounts, delete the data in the accounts. That way you can keep your usernames and logins for various services.

In 2016 I deleted all the tweets I had made over the previous 9 years, and soon after I backed up then cleaned out my FB profile and unfollowed all my contacts. There was a lot of manual labor involved in this because I had auto imported a bunch of stuff early in FBs life, and it was all sort of stuck in there. FBs crappy API and barely functioning admin UI made it slow going, but it was worth it.

As soon as Instagram shows any sign of its popularity waning with my contacts, I'll be deleting all the pics there as well.
