Most of the times when someone uses the words “WordPress” and “community” together the answer is Buddypress.
Regarding your requirements I would say:
- social media login,
- user panel
can be handled well by plugins, but
- content rating,
- output content based on ratings
sounds like something that has to be custom-coded.
But this also depends on what content should be voted on and how the voting should be handled. I know there are buddypress plugins available for rating forum posts and pictures.
I would advise you to just install wordpress + buddypress and some plugins and see if this provides you with 95% or 50% of your requirements. After all it’s not only about if there are plugins available for something but also how they work.
