Personally, from the ones you listed I'd say Weebly, I've used it in the past and is very user friendly. But, I wouldn't use it. I recommend you to build a WordPress site and install the plugin Beaver Builder, it converts pages and post creation in a drag and drop website builder just like that of Weebly and such. It gives you many features to use and if you want to go PRO get yourself either the PRO version or the Standard version. The good thing about this is that you've got to pay only once and you will be able to use the version you upgrade to for as many sites as you want (or have).
The PRO version goes fro $199 and Standard $99. But, using the free lite version works really great as well.
Hope this helps you
