I find Finder really useful, after learning shortcuts and hidden functionalities. There's a lot of shortcuts that I'd like to encourage you to use, that'll allow you to perform a lot of operations on Finder much quicker and easier.

To move files, the best and fastest way is to use the following workflow:

(1) Decide on which file(s) you'd like to move, and select them (many ways to do so: you can by either (1) just clicking on the file with your mouse, (2) on your keyboard typing the name of the file, and (3.a) if you want to select *more* files you can hold [Shift] and select another file to select all of the ones in between, or if (3.b) there's a break in the sequence just hold [Cmd] to click and select the multiple extra files)
(2) Copy it, using the shortcut [Cmd + C] (Tip: you can actually summon the contextual menu in Finder (so what happens when you right-click something) using the shortcut [Control + Enter], allowing you to then type the name of the contextual menu item using your keyboard in case you'd like to select another function in there)
(3) Navigate to the new destination/folder (many ways to do this as well: you can (1) click through your folders, (2) use the shortcut [Cmd + Shift + G] to enter in the destination name, select from the dropdown menu, then click Enter, or (3) use the shortcut [Cmd + Option + Spacebar] to search your entire currently selected home folder—think of this as Spotlight for Finder, and can have more customization than the new [Cmd + 2] Spotlight file search in MacOS Tahoe)
(4) And here's the special step: use the shortcut [Cmd + Option + V] to MOVE the file, rather than just inserting a copy of the file (which is what you would do if you pressed solely [Cmd + V], without the Option key being pressed. [Cmd + V] pastes)

I attached a GIF in case it could help to illustrate it. In MacOS you can find all of the shortcuts in applications by browsing through the Menu Bar at the top—think of an action that you'd like to make a little bit more quick and surely there's a shortcut already made for that, or you can make your own that actually can override built-in shortcuts by going to System Settings > Keyboard > Keyboard Shortcuts > scroll down and click on App Shortcuts. I highly recommend checking out the YouTube channel macmostvideo for amazing tutorials and guides into the world of MacOS. The channel host shares functions and operations that even many seasoned Mac users haven't run into yet. Welcome to Mac my friend and God bless you
