New Commer wants to make his first keyboard but has a lot of problem/requirements/questions

The most durable keycap material is PBT (it means that plastic will never lose texture and shine unlike ABS), and the most durable in terms of legend-printing methods are double-shot and dye sublimation (it means the legend won't fade), you can read more about keycap types here:

You probably won't find many double-shot sets unless you're looking for backlit options, if you want something like colors on the keycap and the legend look for dye sublimation for durability.

PS: Your layout link actually links to a Spotify album. Its not really what I'm liked to listen but I like it, saved it to listen later.
