Basic HTML pages generated by php, python, whatever in the backend would work fine. Using a javascript framework like react or vue or whatever would work fine. Vanilla JS using the simple fetch method on the API to pull in data would be fine. For WordPress, since it's so popular, there could be an extendable WP plugin that would make calling into the end points simple with no coding required. For example, display your TGP page in the main content area, but still have your sidebar and header managed by WP. This could go in a million different directions, I am just saying I like the idea of separation.
