Hello!
How to choose an SSL certificate for a telegram bot?

Answer 1

In what sense "how"? Take whatever you want - and use. If you are subject to prejudice and have nowhere to put money - buy. If you are deprived of these shortcomings - Let`s Encrypt.

Answer 2

in terms of telegrams, a self-signed one is also suitable (they support it), but let's encrypt. If money is not a pity, then buy. A wildcard is not really needed, since all you have is a post request for a webhook to some url like site.site/webhook. SAN is also not particularly necessary. So if purchased, then deshmansky what. (all of the above - if the site does not yet live on this domain)
