For your use cases, either the Air or the Pro will suit you just fine. The question honestly should be of whether or not ProMotion (120Hz Refresh Rate), Face ID, Thunderbolt I/O (instead of normal USB-C), a LiDAR scanner, tandem OLED, or any thing of that sort is important enough for you to spend the extra money. Based on your description of what you do, you really ought to be fine with the M2 Air. Tandem OLED ought to make watching things really nice, but do consider that you are spending $300 more for the privilege.
