I'm looking for syntax like:

aws ec2 describe-security-groups --instance-id i-0xyz

however, the above sub-command doesn't support --instance-id parameter.

I've checked and there are --filters and --query parameters, but I'm not sure about the syntax.

What would be the easiest way to display the description of the security group of the instance?

You can use aws ec2 describe-instances instead, you can specify the id --instance-ids <value> and it will output the security group.

The following one-liner in shell works for me:

aws ec2 describe-security-groups --group-ids $(aws ec2 describe-instances --instance-id $id --query "Reservations[].Instances[].SecurityGroups[].GroupId[]" --output text) --output text

Where $id is my instance-id.

you can use

aws ec2 describe-instances --instance-ids (your Instance id) --query "Reservations[].Instances[].SecurityGroups[].GroupId[]" --output text

replace

(your instance id)
with the specific instance id you are looking for.
