I am wondering about negative consequences if I add a SPF record for a domain used for e-mails. Would the users need to change something in their mail settings?

In short, no. Nothing needs changing on the client.

SPF Records are used by other servers receiving mail from your domain. It gives you the opportunity to state exactly which systems can send mail from your domain name (to combat spoofing).

Mail clients wouldn't need to change anything, SPF lookups are handled entirely on the server-side.

Unfortunately, SPF Records are still not widely used or checked, if they are used they are generally put in Soft-Fail mode. That means the system receiving the mail could still not be sure whether the sending server was valid or not.
