You can use taxonomies in WordPress for this. A simple example with a taxonomy that WordPress already has: you can store as many tags as you like in the backend under Posts > Tags. You can then assign these to your posts. This way, the posts are linked to the tags you have chosen. In the frontend, you can then define that these tags are linked to the post and the respective tag page is opened. There you can then see all the posts that have the same tag.
How you can display the tags on the post in the frontend depends on the theme and page builder you are using.
In theory, you can also create any other taxonomies you like. Plugins such as ACF or Custom Post Type UI can help with this.
