Create a page with a list of termsets and terms + all pages containing these terms

Hi all ...

for the last 5 days i have been searching the internet but i can't find a solution to something simple. Am i overlooking something? Copilot points me to the "Term store" and "Managed data" webparts, but these are not available in Sharepoint online. Chatgpt gives me all the code to make my own webpart. However, i'm no coder and already got stuck installing node.js on my laptop.

Here is what i want to do:

I would like to create a pages that shows:
- Termset

-- Term

--- List of pages with this term

And this for all thermsets and terms in a termgroup.

When i add a termset or term the page should update automaticly.

I'm would like to migrate our internal knowledge base from Wordpress to Sharepoint.
I have a screenshot of how this is currently in Wordpress. Management insists on keeping the same overviews without having to maintain these pages manualy. Thank you for any help on this.
