Again with the caveat that I haven't used a trackpad on a desktop, I doubt that they have the same resolution as a gaming mouse.
On my desktop I use a Logitech G305 at 3200 dpi and, unsurprisingly, takes less than 2 inches to flick it across 2 screens (1920 x 2 / 3200 = 1.2).
On my laptop the trackpad is 3 inches across and takes the whole trackpad width to move the mouse from left to right. I'd figure a resolution of 1920 / 3 = 650 dpi.
I couldn't easily find dpi specs for trackpads so I might be very wrong in my back of the envelope calculations.

The regular plain old wired optical mice do not turn off (they may "dim" a bit when idling, but instantly turn on when moved), and turning off that badly is also not familiar to me from battery-powered optical mice (some, but not all, of them annoyingly need to be clicked to turn on, having to be turned over just sounds nuts to me). By the way they last ages on a fresh pair of non-rechargeable batteries, maybe half a year, could be more or less depending on the mouse and the batteries. On the other hand, it seems that the batteries sense when you need them most, and suddenly cut out without warning right at that moment. Jokes aside, I prefer the wired mice because they are light. The batteries make the wireless version heavier, which in particular was not good for twitch-movement.
Optical mice work directly on most tables, it is often not recommended but you can use them that way.

Best at what? I have yet to see one used in e-sports, so probably not that. Maybe CAD?

I bought an entire small notebook (11.5" touch screen, 4GB memory, 64GB drive) for less than the cost of this!

The marketing blather: RollerMouse Red, unlike a traditional mouse, sits in front of your keyboard instead of to the left or right. This placement eliminates the need for reaching for the mouse and will greatly reduce unnecessary muscle activity in your arms, shoulders, and neck.
And then a screen farther down, they show the users left hand on their contraption farther away from the home row than my left hand is when using the mouse immediately adjacent to my keyboard to the side.
Did you ever see history portrayed as an old man with a wise brow and pulseless heart, weighing all things in the balance of reason?
Is not rather the genius of history like an eternal, imploring maiden, full of fire, with a burning heart and flaming soul, humanly warm and humanly beautiful?

I've had a number of wireless mice over the years. The batteries last for several months. I've never had one that powered itself off and had to 'wake up' to be usable, or if it did, it wasn't noticeable.

A laser pointer. And a cat, hours of fun to be had. (No cats were harmed in the posting of this message).
On a more serious note, I use a wireless optical mouse. Many have an off switch, which solves the battery life and wake-from-sleep issues. I recently bought a cheap and cheerful Bluetooth mouse on eBay which is excellent and saves a USB port.
Update: This mouse actually does USB too so it's a pretty nifty device, I really like it. Trackball mice tend to clag up over time, I would avoid them, and if your optical mouse won't track reliably, use a mouse mat. And yes, you can turn this one off.

Microsoft's Arc Mouse is also an option, it combines the best of the two worlds, portable, it's BlueTrack so expected to work on glass, too.

My RedDragon mouse is wireless and uses a laser. It lasts a good 3 days on a single charge and can be used while charging as well. It has variable speed right on the mouse and other features that I don't currently use (I think it's a lowish-level gaming mouse). It also matches my keyboard

It lasts far longer than my laptop battery, so I'm satisfied.

My Logitech wireless laser mouse goes for week without needing to be recharged. No batteries to replace, just pop it in the charging unit overnight. It is model MX-1000. Unfortunately, it is no longer available. I've had to replace the left-click micro switch a couple of times, but it isn't difficult to do and more recent versions (MX Revolution) of the mouse are not as versatile.

My personal preference is a trackball. I'm currently using the MX Ergo made by Logitech. The M570 is cheaper but, lately, they don't seem to last as long. My wife prefers using a touchpad and a while back we bought her a Logitech K830 keyboard that has a touchpad where the numeric keypad would normally be. It's wireless.
Hope this helps.

I came to prefer using a Wacom Tablet with stylus. Direct mapping from pad to screen meant that I didn’t have to shuffle the mouse over and over to move it across a wide or multiple screens. Some models allow for touch (fingertip / multiple finger) and gestures.
The downside was the desk space it takes. But I got used to it.
Since I retired, I opted for a gaming mouse due to desktop size, and not spending 8 to 12 hours on it. Currently using a wired Roccat mouse. It’s programmable and precise.
It’s all personal preference, so, as another commentator said, all this is opinion.
Good luck

I prefer wireless mice and just to clarify.
I never turn it off and it lasts about a year before I have to change the battery and I use it a lot. Hours a day.

I use a Logitech wireless mouse and a Logitech trackball and alternate them when the batteries run out. The idea is to reduce the chance of OOS by using different muscles.

Eye tracking?
It seems like a hi def web cam should be able to drive it.

The Windows 11 "taskbar" is disgusting. It should be at the left of the screen, with real icons, with text, progress, etc. They downgraded my developer PC to a bloody iPhone.
