Do search engine cares about the security provider used on the website?
Say, the website has initially been using Letsencrypt, and then later migrates to another provider which is using Symantec certificates?
Q1: Will there be a 404 error when the new site is visited?
Q2: What are the issues that I need to be concerned about?
There should not be any kind of error which is because the switch of the site certificate. As long as your certificate is valid and trusted by browsers, you should encounter no issues.
You might change the CA brand due to various reasons, like pricing, no proper support provided, their root certificate got compromised, etc. So is the reason we have multiple CA brands available . CA/B forum is the a forum where all the browsers and Certificate authorities participate and make sure the lives of the netizens are secured.
