Are you looking for advice on some other plugin to use rather than ACF? There are several that will allow you to create fields and also create templates to show them. 2 that spring to mind are “Pods” and “Types and Fields”. There are several others as well if you search the WP repo for custom fields. I cannot give a recommendation for which to use, they each have their own workflow. I don’t use any of them because I like coding templates.
