CMS Recommendations?

Hi Expo’ers,

I have been playing with the platform for a little while now and love it as much as everyone else!

Im building an e-commerce site and was wondering if anyone had any recommendations for a CMS?

My plan is to host on Netlify, is there one that works well with Netlify in particular?

Would be great if it was open source?

Im am obviously doing some research but any help would be great.
