I find switch inputs on my brand new 32" 1440p monitor a bit tedious compared to my almost 20 yr old 20" Ultrasharp where I can cycle through video inputs quickly and easily from a single button on the front panel. That said, most monitors have multiple video inputs, so you wouldn't necessarily need another monitor. I think the same applies for laptop or desktop (not 100% sure on that) In general, mimicing what others have said (I've not directly compared), your best bet tends to be something with a Turing nVidia GPU w/ NVENC support, so GTX 1650 Super or newer/higher. And then you have other expansion options you lose, in exchange for lower power consumption and convenience, with smaller form factor For a given dollar amount, a desktop PC tends to be more powerful, as it can use more electricity and not be thermal constrained. Issue is generally laptops have power constrained CPU & CPUs (there are certain exceptions, and engineering workstation class machines are less constrained, and a lot heavier and more expensive).
