It was a bit to get used to for me as well, I switched fully to Linux around 2020, prior to which I had many years of Windows intuition. I literlally just started with using no fancy features or trying to be a Vim power-user, basically the only keybinds I used where i, w, q, and wq, I learnt dd organically, and have just been learning the odd trick here and there. I still use about 1% of Vim's total capacity, but I already vastly prefer it over Nano for features aside from those behind keybinds. I still turn on mouse mode on Vim, I still use the arrow keys rather than h/j/k/l, but it gets me through my day painlessly.

the best part about learning vim, at least the basic movement and operations, is that pretty much every good application that involves text has a vim mode/plugin which means what you learn can also be used outside of CLI.

learning it takes time, i started with basic movement and then each week incorporated a new command into my workflow. it really does make text manipulation faster, but also if you don't modify text frequently then yeah nano is fine or in a GUI Kate is also great (has a good vim mode and you get a gui so you won't get stuck).
