CISCO WAN without Dedicated/Static IP

I have some CISCO devices (firewalls & switches)

I intend to set up a WAN between two locations but both locations are dynamic IP (residential broadband).

The IP’s of each location do not change regularly but they do change “occasionally”.

I am new to CISCO networking, and have sought documentation about this, but to no avail.

The WAN is not production crucial as it is for private / learning purposes.

Q. Is there any known documentation that would advise the best practise for this kind of network?
