Resources to grow my store?

I started an etsy and shopify store not too long ago but I literally don't know where to go next. I know I'm supposed to market it but ironically, I avoid all platforms (YT, snap, FB, ig, TikTok) besides reddit.

I know the formula to starting an e-commerce store isn't hard (it's growing it that's difficult) but is there any guide or resource I can follow? I know literally nothing about marketing so I need something to follow or guide me.

Thanks.
