Grav may be a good choice if you like the beautiful and smooth things.

I am working on a local install using Craft CMS . Looks promising, but a bit pricey as one uses their commerce.

Jekyll is the one of the best if you are looking for light weight and easily customizable platform.

If you have some experience in Python development you can take a look at Django Mezzanine. It comes with Blog support by default. I think if you just need a blog, you will not need to know Python at all. You will just need to customize the look and feel to what is suitable for you.

There are many ways to create a website, but if you don't have much experience, using a website builder will be the best choice for you, I guess. I haven't tried webflow, but I heard it shows good results. Personally I used one of website builders beautifullife.info/web-design/15-best-free-websit… and was pleased with the final result. It was easy to work with it and it didn't require special coding skills. Hope it helps!
