I'm a newbie in web development (well technically not development but the web infrastructure, CDN/DNS/Nameserver/etc.)

As long as I use CloudFlare, it doesn't matter what host I'm using, right?

I've been thinking of ditching shared hosting and switching to Heroku since it'll be free (and git is always awesome).

If you're behind a CDN then use whatever backend suits your deployment style the best. If you like working with git then GitHub pages and Heroku are both great.
