Answer 3

Start from sections of your site. The URL structure itself has little effect on SEO. Accordingly, first of all, you should think about the client and the sections necessary for easy navigation. According to the sections and do the URL structure.
You also need to be guided by three rules
1- the shorter the URL, the better
2- the most high-frequency keys should be taken into account in the URL (most often it is one)
3- it is desirable that the URL reflects the real structure of the site sections
