Vim is different. It has modes, it has commands all over the keyboard, it has tabs that are not tabs, it has different shortcuts than what you are used to, it lacks basic features and comes with incredibly useful ones you have never thought about, it's a TUI, it's incredibly dumb and incredibly smart at the same time, it puts you in the driver seat, it uses its own weird language for extension, it's old and buggy, etc.

The features you are used to may or may not be built-in or they may or may not require a plugin—or three. The way you are used to handle files may or may not match with Vim's built-in file navigation features. In any case, forcing your usual features and behaviors into Vim is an exercise in futility. You will get more value from learning it properly and leveraging its built-in features than from replicating your previous workflow.
