As a creative graphic designer, how can I capitalize on social media, in order to showcase my talent? And which platform is the most adequate for this particular purpose?

As a graphic designer you have to be creative therefore - find creative way to show your talent. You can sign up to freelancers' websites and if you are good enough - get the projects done.

it is very useful these days

you can show your work "Best of " to a wide network of specialist that you target

& the Best will be Pinterest

then you can use also instagram & facebook to to create your interactive page

Well , There Are Many Ways For you to do so

Lets Start With Digital Illustartion , ( Vector / Vexel ) Art : it can be Quite Good for SHowcasing your Artistic taste and Of Course your Graphic Desiging Skills 

There's Also Maniplulation Field , Which is a Huge and Of Course it can tell alot about your experience of using many platforms related to graphic desiging specially PS.And of course ; Retouching : pretty much one of the most known fields For Ps Users and Common , it can tell alot about your Light and Shadow knowledge , Colors matching and common sense of beauty which of course should be found.And we can't forget about Animation either it was 2d or 3d , by creating short clips about a certain product which can vitally  increase visual reach.In My opinion ; i pretty much think PS Can do All of the previously mentioned ; considering the fact that i'm in love with PS , but Illustartor , and Lightroom can also get those done

Pinterest is highly visual, the majority are female audience, and good for traffic generating if you have a product.

Instagram 70% of the world brands using Instagram as a marketing channel.

Facebook, no comment! everybody use it, so it is a must.

simplify your work, and your content, make it easy for people to understand what you are selling, cause once they got it they will share your posts your page to their relative and friends who might be interested

but when you are making a creative professional content people might not understand this and they will not press like or even share it

In my opinion now a days social media is a very good place to showcase your work with everyone,because now a days everyone are in their many experts,company's,etc.
