I created a section template that has few client logos.
I was able to insert that to the page. Fine, this works, but it seems that it creates a local copy of the elements in the template. If I have several pages I want to reference the same template in, now I have to go and update every page separately.
Instead I would like to reference a template so that I have one central copy of the data that can be updated later, thus having all references updated automatically.
In my understanding this is how footer and header work for example.
Yes you can do that with templates no problem. Have a look at this video and I explain how.
Ps: There are no dumb questions 
Thanks!
To clarify what I was looking for was just the “Template” element that I can add to the page as reference to the templates, silly me.
If I understood this is different to using the Template browser and using “insert”, as that just copypastes whatever is in the template to the page that can be adjusted then, correct?

Yes this is different then what I showed you. What you are describing above is a copy and paste of that content from the template. From my experience, just inserting is never a good idea unless the template that you are inserting is a boilerplate of some sort. But when you want to have that content dynamic, this is not a good idea.
What I showed you here injects that template (and it’s content) into the page you want. So when you need to make a change, you change it on the template, and it then populates that change to wherever that template element is placed.
