How do i change header fonts for sections on sense theme?

Hi i have a “featured product section” and a “new arrival section” the font for them is too big and the theme setting for sense is already on “small” how do i change the font size to smaller than that? when the product is clicked on on desktop the title is too big as well . also how would i change the font to those sections after?

any help is highly appreciated. here is an example
