Which plan to choose CloudFlare?

Question

cloudflare

I am interested in the following questions:
1. Is it possible to connect Let's Encrypt Wildcard certificates? If possible, with the possibility of automatic renewal.
2. 10 million requests per month is 10 million page opens? Or is it about 20 requests when opening one page? Those. each uploaded image is a separate request.
3. Do I need to buy additional Cloudfare services, except for the main one. Is there a need for this?

Answer 1

1 From $ 200 you can have your own ssl certificates, but is it necessary on cloudflare, because he himself provides wildcard
certificates. You can buy dedicated wildcard certificates from them for $5 to show only your site. You can also quickly get letsencypt certificates through the dns plugin, but you have to use it without cloud protection
2 The picture is already a request.
3 is optional
