Not to be “that guy”, but you can use a gui file manager to access your files the same way you do so in windows. Most of them support ssh keys as well. If you’d like to check out the cli stuff, nnn or ranger can be useful. Something like midnight as abckup is good too. Definitely install fzf on both your vps and local machine. You can also go over board and run xorg over ssh and run a small window manager, maybe awesomewm or even xfce (not that small but works fine).
