Pagination in Woocommerce

#1
I have online store.

The first page (site.com/page/1) contains: rel = canonical and index, follow

Site.com/page/2 has the same (rel = canonical and index, follow), meta tags are the same as on the first page



Which option is correct (since opinions are very different):

1. Close * .com / page / n in Robots.txt

2. Put on the pagination page (* .com / page / n) noindex, follow

3. From the pagination page (* .com / page / n) point rel = canonical to site.com/page/1 (prev, next to the previous and next pages)
