Christina, please don't take this the wrong way, but someone who likes to work quickly, it sounds like you are missing a few tricks.
Starting with the Move and Artboard shortcuts, if you never use Artboards, why does it have a shortcut. Like you, I very rarely use Artboards, bit I chose to keep it in my custom toolbar because it helps me arrange the toolbar. I have removed the shortcut however (just select it and delete it) so I know that when I hit the V key I _always_ get the move tool. From what you can see of the Edit Toolbar Panel in my screenshot, the W key toggles Object and Quick Select tools and never the Magic Wand tool, because its quicker. Having a double row with most of the tool icons isolated means I can also use the mouse or stylus.
Another thing that has always puzzled me is why would we use the Shift key to toggle between tools with the same shortcut? Hitting the shortcut without the Modifier is easier and works the same.
Do you work on a laptop? I ask because having limited screen space is the only reason I can think of why a person would use the default Function key shortcuts. Otherwise they are a solid gold resource that can be put to better use. I use them to trigger short Actions that set and reset my custom workspaces, make Smart Object, new Smart Object Via Copy, Rasterise layer (I hate that right click menu. I also use them to add canvas, trim, toggle Lazy Nezumi Pro on and off and select presets etc. It is a wonderful feeling making those things happen with a single key press.
Bring it all together with custom workspaces, and save your custom toolbars and shortcuts with those workspaces. Appart from the convenience of this, it is the best way I know of saving your custom shortcuts. I answer a post a few days ago from a user who was losing his custom shortcuts every time he updated. If he had them saved with a workspace then resetting that workspace would retrive the shortcuts.
What is really cool is repurposing the same shortcuts according to context. Michael Ninness did an excellent workshop at MAX in 2014 (I think) called Photoshop Power Shortcuts that I loved, and I still use a lot of his custom shortcuts like these arrange windows. However, I use Free Transform Step & Repeat a lot (Shift Ctrl Alt T) so I switch to a modified Essentials (with F6) to do that, and hit F5 to go back to my three screen workspace.
These things can REALLY speed up your workflow.
BTW My current favourite shortcut is F12 Make Smart Oject because I use it multiple times with every project, and like I said, I hate the right click and search that list (that gets long with every update).
