Nice tutorial thanks

Definitely not a waste of time, surely helpful to a lot of people 🙂👍 But you could have it much easier: it is actually not necessary to change the Miter Outer to Arc and the Superellipse profile to 1. When you use the Weight method to bevel all the relevant edges, you can leave the Miter Outer at Sharp and the Superellipse at 0.5 and have more than two segments. Because the Superellipse setting at 1 (or rather everything > 0.5) is actually what is creating these bumps whenever the segments are set to an odd number. For example, you have set them to 3 at first and then you decrease them to 2, an even number. But you could also increase them to 4 or 6 or 8 to get rid of the bumps. Anyway, those bumps will not occur if you leave the Profile at 0.5 and leave the Miter Outer at the default Sharp as well. So, to cut a long story short: the whole trick is the bevel weight for those corner edges - because actually in the geometry you show in the video, the Miter Outer setting is irrelevant and does not change anything (you can enable Wireframe in the overlays to compare). Only if you set Miter Inner to Arc it will change the bevel. And if one wants all edges beveled like you do at first with setting all weights to 1, the quickest way to do this is setting the Bevel modifier's Limit Method to None instead of Weight. This will bevel all edges, regardless of weight or angle and get rid of the nasty subdivided look immediately. The Weight method is only needed when you want to have control over how much an edge is beveled or if at all.
