This "Kingdom" was entirely built playing Survival mode, on a Chromebook.
Using a 2019 Google Pixelbook Go Chromebook (8th Core i5, 8gb RAM)
(This gameplay was recorded on an Android smartphone, specifically a Pixel 8, so the chunks can be set to 24, instead of the modest 7 chunks my Chromebook can handle)
This video aims to show that even an old Chromebook can run Minecraft (Bedrock Edition) in a decent way.
Keyboard, trackpad, mouse, controller and touchscreen controls work perfectly.
Overall my experience playing Minecraft on ChromeOS has been fantastic.
