I would have recommended you mine or venera.social. They’re around 10 years old or something, so quite some time. But they’ve temporarily closed signups. nerdica.net and anonsys.net have also been around for quite some time, although the former had some problems last year and lost years of database. ouch.

Then there’s social.trom.tf, which has some of the most wonderful custom themes I’ve seen on Friendica, but their opinions on stuff are a bit weird for me…

For the rest I don’t know that much.
