Cms of a blog, store based on "crud"?

Question

Blogs

It is necessary to develop a blog and a store.
I'm trying to find cms on which to implement them, and I ran into a couple of problems-questions:
1. Before that, I made a blog once, on asp core. Admin and cms were self-written. As a conclusion, asp core tools are superfluous for such tasks, and reinventing the wheel (cms, admin panel) is just a waste of time.
2. The obvious choice for such tasks would be Wordpress, etc. But after watching a couple of videos and lessons, I saw that it was impossible to do without writing backend php, no matter how it came to sql, plus some templates and plugins, is it possible here to screw a custom design.... (In general, there are too many gestures for etching, as for me, tasks)
What do I want and what is the question:
I want to implement projects in the form of a SPA that will send requests like getPost, getPosts, etc., and I myself will decide how to display them (using Vue.js). In my opinion, it’s easier and faster to make a spa than to understand the concept of templates, etc.. (In my understanding, cms should look like this)
That is, cms that:
- can perform get requests,
etc. track content;
- has xss security checks and so on...
- other blog/shop features
Are there any?

Answer 1

For the back (CMS):
1. https://github.com/agentejo/cockpit
2. https://directus.io/
For the front (block loading of page parts):
includeHTML

Answer 2

It's called headless CMS.

Answer 3

You can put 2 engines - separately for the online store, separately for the blog.
They will work on different URLs, they will not interfere with each other.
You can take one Woocommerce, there is a blog, there is a store

Answer 4

For a blog, it's often easiest to deploy WordPress in a subfolder

Answer 5

So if you have already worked with ASP Net, write api and do the frontend as you like.
