wildcard is great if you have lot of subdomain . instead of assign the certificate to each subdomain you can have all for your sobdomain so all of them can be https easily

i used to use lets encrypt but since i use cloudflare i cannot use that anymore for free . you need to pay to use your own cert on cloudflare . but luckily cloudflare also offer free ssl and you dont need to renew it every 3 month but it is shared with other people so your certificate can also be used on other people site since it is shared
