Is Let's Encrypt good enough for a business site?

Yes. Browsers treat it exactly like any other domain validated certificate. Paid certificates differ in warranty and organisation validation, not in encryption.

How long is the certificate valid?

90 days, renewed automatically well before that. You do not need to touch it.

Can I get one certificate for several domains on the same VPS?

Yes, add more -d flags, or simply run Certbot once per site. One certificate per site is easier to manage.

Does a wildcard certificate work?

Yes, but wildcards require the DNS challenge, so you need API access to your DNS provider or a manual TXT record at renewal time.

What about email over SSL?

Mail services use their own certificate. If you host mail elsewhere, see how do I set up Google Workspace or Microsoft 365 MX records .
