Use one blog or multiple blogs on same website?

Curious what everyone's take is on whether to use a single blog, or multiple blogs on the same website, and pros and cons of each strategy.

Is one better than the other, and what reasons did you decide to choose one over the other?

To add some context, I'm building a website that will focus primarily on articles as my content. All articles will cater to anyone interested in the website's topic.  However, I'd like to group the articles by skill level (beginners who need a "101" crash course on the topic vs. those who are more advanced with the topic).

I'm leaning toward the Multiple Blog format to achieve this division, but as mentioned above, all articles cater to anyone, so there's some overlap.  I worry that with setting up multiple blogs, I'll have a harder time referencing pertinent posts from "the other blog"

Single Blog

• Pros: Can strategically use categories and tags as a way of filtering the public-facing summary blocks, or creating direct links to see all posts with a specific category.
• Cons: Hard to keep organized on the backend once you have dozens of posts since Squarespace's blog view is not that robust.  Also, all posts will share the same URL slug

Multiple Blogs

• Pros: Ability to assign a different URL slugs, replacing categories and tags as an organizational tool.
• Cons: Can't combine multiple blogs on a single summary block
