I would recommend a less wide angle. If you have the space so you can get a 50mm, you'll get much better bokeh than a 20mm.

The thing with shooting WFO, you'll have tissue paper thin focal plane. Moving forward or leaning back could throw you out of focus.

A modern camera like a Sony A6400 (which I use) has facial focus tracking and deals with this quite well. I use a 16mm prime lens for my video calls -- 50mm would be way too close for my facial distance (about 2 feet from the lens).
