my $ua = LWP::UserAgent->new(
ssl_opts => {
SSL_verify_callback => sub {
my ($ok, $ctx_store) = #_;
my $cert = Net::SSLeay::X509_STORE_CTX_get_current_cert($ctx_store);

Answer 1

For the URL that you show in your example, there are three certificates: the root certificate from USERTrust, the intermediate certificate from Sectigo, and the website certificate. The dates correspond to the expiration of each of those. The Difference Between Root Certificates and Intermediate Certificates is a good read.
You likely want the closest date, which should be the expiry of the user certificate.
