What better Link Structure, use?

Hello guys, alright?
I am developing a platform for online courses and i'm doubts which use link structure. I would like your help on the best option in this case.

Here are some options such as:

To CATEGORIES:
1. domain.com/name-category/
2. domain.com/courses/name-category/
3. domain.com/courses-online/nome-da-categoria/
4. domain.com/category/name-category/

For INDIVIDUAL COURSE:
1. domain.com/name-course/
3. domain.com/course/name-course/
2. domain.com/courses/name-course/
4. domain.com/course/category/name-course/
5. domain.com/category/course/name-course/

In your opinion what is the best structure?

A big hug and await answers!

Are you ever wanting to rank for the courses or category related keywords? If so you will want a menu page for those anyway so having that structure makes sense. Whats your strategy?

You will have to structure your content in accordance with your ranking needs.

I would like to index both (courses and categories) but giving priority to individual courses is the target point.

My strategy is:
Courses and categories will be relating to generating authority between pages.

I think in:

To CATEGORIES:
domain.com/courses/name-category/

for COURSES:
domain.com/course/name-course/

As you can see the slug category is plural.

It is a good structure?
