Before I start creating something from scratch, do you have a recommendation to a TLS setup for a local network? Several servers, several clients.

Do I set up a CA and import certs to all devices on the network?
Can I use the cert for my domain.org I got from a public CA to create my own certs for local-only subdomain.domain.org? Is there a simple (!) tooling for this so I don't have to script it myself?
