Change Home Page to Dynamic Front Page without losing current content

Hello,

This is my WordPress site:

https://lobsterbird.com

I recently created a new page on my site (“Scribbles”) that I would like to make posts on but differentiate from my main blog on the home page. In other words, I would like to make posts on this page but I do not want these posts to appear on my home page.

Under the Menu section, my home page is currently labeled “custom” and not “page” like the other pages in my menu. Up until this point, I have just been adding new blog posts and they have been appearing on this home page.

I am unclear whether I should change my front page to a “Static Page with Blog Posts” or a “Dynamic Front Page.” Currently this is not even an option with my home page (I suspect because it is labeled custom and not page?)

Furthermore, does it make more sense to leave it as is and install a plugin that will add posts to my Scribbles page?

Thank you for advising!
