Looking to install arch, what should i know?

im currently using endeavouros (based on arch), and i think i should just switch over to arch. Im currently reading over the installation guide on the wiki. what should i know before installing it? Ive heard of archinstall, and should i use it?

Edit: i have a nvidia gtx 1660 ti, so id need to install the drivers for that

Edit2: i also want to somewhat follow this for creating rices: https://namishh.me/blog/ricing/

Edit3: about how long would it take to get to the point of installing steam?
