I watched the same videos, and will be looking at laptops over the next few months, so may well go the AMD route myself.
When I bought my laptop a couple of years ago, I made sure that it had TB3 for future-proofing, but I have yet to use it, and I suspect that I'll never use it over the course of the laptop's lifetime (and I have a tendency to keep my laptops in use for a long time).
I think having USB-C is good enough for the majority of "normal" users, although I can appreciate that TB is probably a must have for some power users.
I was only pointing it out as pretty much the only thing that's likely to be a significant issue for many, especially if you're doing any kind of casual gaming while wanting to dock, vs plugin a few separate items. I use a desktop at home, so not as concerned personally.
Not sure if you're aware, but you're presumably using your dock in a config where it's using DisplayLink for the display output. Configurations exist that do HDMI/DisplayPort passthrough over USB/TB, which have native performance.
I was watching Linus Tech Tips[1] video yesterday, and Asus had a new array of nice laptops (albeit, gaming laptops) that were AMD based, including a 13" one with decent AMD CPUs
