How can I style Shop Variants and 'Additional Info'?

Hi,

I would like to achieve the following shop item changes:

1). Change font of shop variants to 'Poppins' (to match the rest of the website).
2). Reduce the box sizes of variants options (i.e. S, M, L...) and "Quantity".
3). Reduce the distance between separator lines of the Accordian found in the Additional Info section.

Please refer to attachments for clearer directions.

Any help would be truly appreciated.

Thanks!
