We are also using the "Layout_Lisbon", but on Wide desktop screens the content is really stretched and does not look great.
I was very excited when I came across this post. I changed our pages and then realized it only fixes part of the problem.
Adding the "Website_Section" to the "MainContent" placeholder does the trick for the main content, but the other placeholders ("Breadcrumbs", "Title", "Actions", etc) are still stretched across the entire width, which doesn't look tidy and neat.
When setting the Theme's Grid properties to Fluid with a max width, it gives the expectation that the "Layout_Lisbon" would adjust accordingly, but only the header and menu does.
It would be great if all the placeholders in the "Layout_Lisbon" would adjust.
You're probably wondering why not just use the "Layout_Website" with "Website_Title" and "Website_Section". I did look at it and this is our conundrum, we want the placeholders available in "Layout_Lisbon" but does not want the "ultra stretched" look on wide desktops.
What to do? What to do?
