Using CMS - Automatically display Products or Services on a Dynamic page sorted by Category & Sub category

Question:
I’m creating a website for a Beauty Salon.
The Salon has c.250 services or treatments available.
These are categorised into 11 main categories and each category has multiple sub categories.
I am trying to build a dynamic page using the CMS function and I’m struggling to work out how to automatically display each page broken into sections to display the various treatments available in a sub category.
For example, the “Hair” category has 5 Sub categories (Hair Cuts, Hair Colouring, Hair Styling, Hair Treatments & Hair Extensions)

For simple management, I’d like to build these pages using the CMS tool but I’d like each category page to automatically display each relevant sub-category and the treatments available in each as I build it.
I can’t seem to work out how to do that and I’m trying to avoid manually building each sub category as this will complicate any future changes.
For context, there is no e-commerce element on this site (a booking link will take customers to an external 3rd-party booking platform) so I’m not using an wix e-commerce booking or transactional elements.

Can anyone help or advise?

Additional information:
Apologies if this is not the right forum for a question like this. I am new to Wix Studio and this is the first time I’ve reached out to the community for help

you can set the filters on each dataset to display what you want. you can add multiple of the same dataset with different filters for each.

Thanks @Dan_Suhr - I’m just not sure I know how to do that (…like I said, I’m relatively new to Studio).
Is there any advice you can give me (or a resource you could point me to) to figure out how to do that?

This may help

there are plenty of youtube videoas if you search aswell.
