Customise and Rename archive pages

Hello,
I hope you can help me with a couple of questions. I have created a few custom post types and taxonomies while playing with an experimental site and am simply trying to sort out the structure before thinking about anything else.

I created a custom post type (let’s say it was called ‘bakers’) with a simple plugin.
I then added a two taxonomies for this cpt called ‘counties’ and ‘area’ via functions.php.
One contains a list of UK counties, the other a list of postcode areas.
I created a batch of custom post fields via the ACF plugin, linked to the ‘bakers’ post type.

I created a renamed single.php in my child theme, called it single-bakers.php and found the relevant code for functions.php so that it shows the correct post title (‘Billy’s Bread’ instead of ‘blog’). That’s fine.

However, what I also need to do is create customised archive pages to display listings of the above single custom posts.
One archive page, for example, will be “London” and this should include all listings with this taxonomy. And so on.

I assume this is output via a standard archive page and so all I have to do is clone and edit one of the standard php files, but am not sure. Which one do I need to customise? Secondly, what code would I need to add to functions in order to get these archive pages to show the correct name?

Many thanks for any help.
