Migrating wordpress.com blog site (not wordpress.org) to wordpress.org or Shopify web-site?

Hello there! I want to start a blog site and not have to pay any internet hosting for it. With that claimed, I was heading to use [wordpress.com](https://wordpress.com) to start the site and start out to construct it out. Following it starts to gain traction, I’d like to eventually migrate it from [wordpress.com](https://wordpress.com) to an actual wordpress site utilizing a concept or a shopify internet site. With that claimed, I have a several questions:

1. Is there a improved blog site system to do this with than [wordpress.com](https://wordpress.com)? I.e., a greater web site platform that will make it possible for transferring to a whole fledged site in the potential significantly a lot easier?
2. Is there a way I can migrate all the facts (meta info, putting up time, images, textual content, formatting, and so forth.) from the wordpress.com site to a wordpress.org or Shopify internet site? Thanks!
