Hyprland uses mostly keybinds, though you can bind some actions to your scroll wheel.
You can definitely use something like waybar to create a custom interface that you can interact with your mouse or even touchscreen.
The beauty of using something like hyprland, sway, niri, etc. is that it is entirely up to you how your computer works, with every person pretty much getting their own custom desktop environment in the end.
I've been running Linux exclusively on my laptop for about 5 years.
I went from Manjaro, to EndeavourOS, then to Arch - using KDE, Xfce, Gnome, and eventually landing on hyprland.
There was a few games that I played that were exclusive to Windows, so I kept Win10 on my desktop PC and kept tweaking it to match my Linux setup.
But once I was done with those games and the Win10 EOL approaching, I was reminded of that Omni-Man meme, "Look what they need to mimic a fraction of our power". My system had so many registry edits and applications/integrations just to imitate Linux, why not just go for the real deal?
I had to fiddle with it for a while when I moved my main machine over to Linux a few months ago, but that's mostly on me because I chose Arch & Hyprland.
If I had gone with a mainstream distro with a "nvidia" variant, it would have likely just worked out of the gate.
If you have an old laptop, put Linux on it, get comfortable using it. Then when you are ready, make the full switch on your main computer.
I have used Linux for a few years mostly on my servers, but that's what I did to get used to the desktop experience. I setup a second SSD to have the option of dual booting if I needed it. That was back in March and I haven't booted into Windows once.
It would be the hand-me-down of all hand-me-downs, but it would be the most optimized machine that has ever existed.
