I found The Creativity SMP and it is a modded Forge server on 1.20.1. It is built around the Create mod with a bunch of add ons like create nuclear and clockwork and more.
It also mixes in military style mods like warium and superb warfare so you can do tech builds and also mess with war gear. There is an economy on the server and the admins seem solid.
Cracked players can join. Valkyrien Skies plus clockwork and eureka are in so ships and flying stuff are part of the vibe. Superfarms are allowed too.
It is still pretty new with a small playerbase that is growing. The modpack is kinda heavy at around 90 mods and you might see some small lag from internet sometimes.
