Webcam on Intel may not work due to drivers that Intel hasn’t written/upstreamed for IPU6 cameras. Looks like it’s in the work now… for certain sensors. Intel has taken literal years to get anything out. the Core Ultra 200 series is out but drivers for these webcams which have in use since Tiger lake (almost half a decade ago!!) still don’t work.

Nor the integrated cameras or the IR camera worked out of the box on my laptop. Some hacks could be done to make it work but it breaks after the system is updated. It never worked when I needed it and image quality was limited to 720p and worse. From what I understand, current methods to get the camera to work use minimal software processing to process the images, instead of the dedicated silicon.
Not all Intel laptops use IPU6. I know some HPs do not.
Haven’t had many issues with the Intel AX211. Very rarely, the wifi settings will disappear after my laptop suspends and a reboot is needed.
The battery capacity also doesn’t seem very big, I’m not sure how efficient the AMD CPU is but I’d be worried that Intel would deliver less battery life.
GPU performance might also be better on AMD? (haven’t checked).
I’ve used an Acer Spin 5 and Dell Latitude 7440 with Kubuntu, Ubuntu, Arch, Fedora and NixOS over the years without many issues.
I’ve heard that the x360 laptop you have may be a little troublesome but you can always test things out on a live Linux USB.
Ofc, there are a few x360 laptops so it might not apply, I’d encourage you to just give it a go with a live USB.
For using your stylus for note taking, I’d recommend trying Xournal++ and/or Rnote
