Thanks for the input, Gianluca. I'm actually a dev myself and am about to abandon all these open-source platforms for a static site, but I do need a blog. It's a terrible case really, but there are absolutely no platforms built first on top of a multi-language framework. You either need a plugin, a module, a different store view, etc. Unbelievably short sided in my opinion, but that's where we're at. New open-source packages like Grav and PageKit don't support multiple languages, either. Just baffling! And SEO standards are flat out being ignored even most of the hosted platforms. WTF?
FYI, Odoo is an amazing piece of software, but their new CMS is far from ready. There is no URL redirect feature; no structured data; unfriendly URLs with post IDs and underscores; dev unfriendly--you'll really need to dive into the code to make changes, override, or customizations. On performance, Odoo runs on it's own openerp server through a Nginx/Apache proxy. All-in-all, the language support is ok and the design features are pretty cool, but these very capable developers almost completely ignored performance and SEO best practices. In my opinion, it will take years for this platform to compete with Magento or Wordpress as an viable SMB solution. There just isn't an easy migration path to Odoo, and it's too much work for no real advantage over the other packages.
Seems like developing a multi-lingual, multi-currency, e-commerce platform that follows current SEO recommendations would be a huge step for mankind. Still looking...
