I am trying have a side column on the left with fixed width, and then, on the right a normal Bootstrap container-fluid.

A fixed-fluid layout is possible in Bootstrap 3, but now that Bootstrap 4 is flexbox this layout is much easier. You just need to enable flexbox, and make a few simple adjustments to set the width of your fixed side column flex: 0 0 300px;, and then flex: 1; on your main column to fill remaining width...

Here's a simpler update for the latest Bootstrap 4 which is flexbox by default:
Bootstrap 4 Alpha 6 or Beta http://codeply.com/go/V9UQrvLWwz
@media (min-width: 576px) {
.sidebar {
max-width: 280px;
}
}
Main (fluid width...)
