Hello,
I saw the screenshot you attached. Please Go to >> Theme Settings >> Typography >> Advanced Typography >> Select the Module where you want to apply these changes.
Screenshot for Clarification: https://www.screencast.com/t/UMCkiBMPUYS
You can target the following classes respectively:
1) I visited the website the first option you mentioned in the screenshot is not appearing on the website please make sure that the module is enabled or you can share the specific page.
2) .woodmart-products-per-page .per-page-title
3) .woocommerce-ordering .orderby

If you are unable to change the typography of those sections then tell me i will check it myself and change it for you.
Best Regards.
