I’m in the same boat, I don’t like Finder (better than Windows Explorer though), nor do I like default macOS files / folders dialogs, and I really dislike drag and drop behavior on macOS
I dont understand why we are stuck in stone’s age with filesystems GUI

In the app you can have a dual pane with two folders side-by-side and select the file(s) you want to move/copy to the other folder and right click or open the command palette to do the operation, so you do not have to drag them (though dragging still works too). It's also possible to cut files with CMD + X and paste them somewhere else with CMD + V.
I prefer Windows Explorer's interface, where the folders are on the left side and the files on the right.
I wish Finder had that view.
One thing worth knowing is in the mac file dialogs you can drop a file from finder into these and it will change directory to where that file is.
The other thing is in most apps in the title bar there is an icon. Drag that to finder and it saves the file. Kinda Risc os style.
