Question

Search Engine Optimization

Hello everyone and thanks in advance.
Situation:
There is a site on which there is a "term" (taxonomy) in which there are additional headings and, accordingly, posts.
There is a page with services, let's say "FL Services". When you are on it, you see the following menu:
1. ServicesFL (made in the form of a page with a URL http://sait.ru/uslugi/grazhdanam/)
1.1. Coloring (link to the terma category with url http://sait.ru/uslugA/pokraska/Displayed via archive.php with links to posts linked to this category)
1.1.1. Painting with blue paint (link to the post linked to the terma category with the url

http://sait.ru/uslugi/grazhdanam/pokraska-sinii-kraskoi/

Displayed via single post template (single.php))
1.1.2. Painting with white paint (link to the post linked to the terma category with the url

http://sait.ru/uslugi/grazhdanam/pokraska-beloi-kraskoi/

Displayed via single post template (single.php))
1.2. Break (link to terma page with url http://sait.ru/uslugi/grazhdanam/slomat/Displayed via template page-uslugi-fl.php (parent page))
1.2.1. Break with a hammer (link to terma page with url

http://sait.ru/uslugi/grazhdanam/slomat/slomat-molotkom/

Displayed via the page-uslugi-fl.php template. Is a child page of the parent page "Break")
1.2.2. Break with hands (link to terma page with url

http://sait.ru/uslugi/grazhdanam/slomat/slomat-rukami/

Displayed via the page-uslugi-fl.php template. Is a child page of the parent page "Break")
Based on the above, it turns out that when you go to any page (1. / 1.1.1. / 1.1.2. / 1.2 / 1.2.1. / 1.2.2.) we get the page through the correct template. And when you switch to 1.1. - respectively, on the archive page with the output of all posts associated with this "category".
In principle, visually not bad, but the following things confuse:
1st: breadcrumbs look like a full path only when the page is implemented as a child of the parent.
Type of url (according to the type of daughter):

http://sait.ru/uslugi/grazhdanam/slomat/slomat-rukami/

Type of way (HK):

Главная > Услуги гражданам > Сломать > Сломать руками

2nd: breadcrumbs look like an incomplete path to the page.
Url type (via "category"):

http://sait.ru/uslugi/grazhdanam/pokraska-sinii-kraskoi/

Type of way (HK):

Главная > Услуги гражданам > Покраска синей краской

3rd: On the archive page, the url view (through the "category"): http://sait.ru/uslugA/pokraska/and links attached to this "category" with thumbnail + excerpt + permalink ("read more").
4th: How will the search engines react to this?
Question:
1. Is it worth bothering with this?
2. If you leave it as it is, maybe you should make it so that the archive page has a "go back" link (for convenience)?
