edit at 16:9 [1920x1080]; embed the 4:3 ones so that their height = 1080; those will display with a border R/L; pick a background color [project settings] that looks good

Nice response, Kayakman!
EJ, If you're combining .trec recordings, some of which are 4:3 and others 16:9, then Kayakman's approach is simple.
If you're combining .jpg images of 4:3 slides in a production, select all of them at once and edit as he suggests, then continue to the next batch. More work, same result.

To add to whats already posted.
When I'm working with media of mixed aspect ratios.

For starters, I would determine the resolution of my media "Overall".
4x3 is an acquainted ratio. It practically screams I'm Low Resolution by default.

Computer generated 16 x 9 images are generally full HD images or higher.   "1920 x 1080"  
If you determine the 4 x 3 images are 1024 x 768 or lower.
I would edit at 1280 x 720. Why?

Generally speaking.
High resolution images can downscale with less overall degradation and blurring.
Things go south pretty fast if you up-scale low res media.
If the 16 x 9 images are of a very high resolution. A happy medium of 1080p may indeed be the best choice.

As far as the black bars go.
I don't care for solid colored sidebars.They stand out.

From where I sit, it has the look of a quickly thrown together presentation with no eye for detail. 

I prefer to add low opacity backgrounds. This image has a Bokeh background at around 20% opacity.
Any image or video under the sun can do the job.
One should chose colors that blend well with the imagery.

The goal is not only to obscure the sidebars.
You should chose something thats appealing to the eyes. In case someone looks at them.

Blurring should be applied in most cases. Blurred edges blend seamlessly in most cases.

Hope this helps,

One addition to the excellent advice above:  If all of the doctored slides use the same resize+crop, remember that you can right-click on one "perfect" slide and copy the visual properties, which you can then apply with a right-click "paste visual properties" to every other slide in need of correction.  You can even apply it to them all at once by selecting the 3:4 slides (easiest to do if you keep them on a separate layer).
