Hi my friend. Sorry for the late response here. As I'm excited to inform that this option is now available on the editor V7. If you are using V6, feel free to reach the CS support team and ask them to upgrade it for you!
I would like to thank you for your suggestion on improving GemPages' User Experience.
Currently, GemPages doesn't have font-weight configuration for Product Title and Cart Button elements in the sidebar.
But you can customize Product Title's and Cart Button's font-weight properties using our Edit Code feature in GemPages' Editor. Please contact our support and we'll help you edit these widgets to your specification.

As for the Text Block element, you can change font-weight to Bold by selecting the text you want to be bold inside the Text Block element and select "B" (stands for Bold) in Text Block Helper Bar. I have attached a screenshot for your convenience.
Yes that is true, but is not handy. Would be a nice feature that will save everyone time.
For the text-block also there would be nice to have different font-weight so you can have in your hand multiple options when you design. I know about the bold option but doesn't help much.
Yes, I totally agree with you on this.
The lacking of font-weight property customization is a problem that we need to address to help shop owner's template building experience much more enjoyable and save their time as well.
We actually have plan to solve this problem in our Product Development Roadmap.
Please stay tuned for our future updates!
