1 Regular Site + 1 CMS, What's the Best Way?

Hi, I already have a regular webflow site to host a design portfolio. I’m now looking to start an entirely separate blog with CMS.

Based on what I understand so far, there’s a separate plan meant for CMS. Now I’m trying to figure out the best option for hosting while minimizing expenses.

I’m hoping to continue with the current old pricing that I have had for a few years for another year but really don’t know the best way to approach it with another separate blog. All domain matters will be handled by me again so any advice is totally welcome because. Thanks in advance.
