Hello,
1- You can try out the following Custom Selector in this regard on your Site under the Dashboard > Theme Settings > Typography > Advanced > + Add Rule > in that you need to select Custom Selector > then you need to paste the below-given CSS class:
.wd-tabs-header .wd-nav-tabs-wrapper ul li a span
After that you can set the Font adjustments accordingly. See this image for reference: https://ibb.co/5sQpmT3
For the Single big Tab header title, you can try out the following Custom Selector:
.wd-tabs-header .tabs-name .tabs-text
To use this for Font adjustment, the same above method needs to be followed for this too.
2- Actually, that Trust Badge Image is added through using the Custom Single Product Layout that you can make under the Dashboard > Layouts > Single Product using the Theme’s Layout Builder.
You can get more information regarding that here: https://xtemos.com/docs-topic/single-product-page-builder/

Here is the Image link that was used: https://blackpearlspro.com/woodmart_support/wp-content/uploads/2022/09/guaranteed-safe-checkout-bordered.jpg
And under the Custom Single Product Layout, the Image or SVG Theme element was used to add that: https://ibb.co/9ZB8Q7s
Best Regards.
