Rinzai is a modern and minimalist theme for blogs, also good for business websites. Demo at https://demo.webminimalism.com/rinzai/ – since version 1.0.6 it has Yoast SEO breadcrumbs support, page templates with sidebar and without, new styling for post and page featured images, narrower content width for beter user experience, 100% valid markup checked against W3C Validator service and now theme supports vk.com and odnoklassniki.ru social icons. Also I did some small changes in styling. Check demo and ask any questions via email. By the way, what do you think about integrating WooCommerce support into this theme?
