How to Choose a Keyboard and Mouse for a Home Desk
Replace a keyboard or a mouse only when the size or the hand position is the problem. Depth, wrist line, and hand choice come before a new device.

Decide the keyboard and the mouse separately. One can be the wrong depth while the other is fine. Start with the desk surface you already measured, not with a feature list.
The wrist line to measure against
The Canadian Centre for Occupational Health and Safety says hands, wrists, and forearms should be straight, in line, and roughly parallel to the floor, with elbows close to the body and bent at about 90 degrees. It also says the keyboard and mouse should stay aligned when you raise a sit/stand desk, in the same way you align them while sitting.
Put your forearms on the desk in that position and mark where the keyboard’s front edge would start. Measure from that mark to the back of the clear area, before the monitor stand. That distance is the keyboard depth you can use. Then measure the clear width.
If the desk is too high for a 90 degree elbow, fix the chair or the desk before you buy an input device. A new keyboard will not lower the top. The desk measurement is in how to measure a standing desk. The chair measurement is in how to choose an office chair size.
Two products
Confirm the orientation drawing on Logitech’s MX Keys S page if the listing shows one. The page says the keyboard connects by Bluetooth Low Energy or the included Logi Bolt receiver, and that it is not compatible with other Logitech USB receivers.
The Lift is a different setup from the CCOHS line, which keeps the forearms roughly parallel to the floor. If you want that parallel position, this mouse is the wrong shape.
Logitech also says a left-handed Lift model exists. The listing has to name the hand. A right-handed unit is the wrong product for a left hand even when the dimensions match.
When not to buy
Skip a new keyboard when the one you have is already shorter than the clear depth and your wrists stay straight. Skip a new mouse when the current one lets you keep the wrist in line with the forearm. Skip the Lift when you specifically want the parallel-forearm position CCOHS describes. Skip either Logitech product when the computer cannot use Bluetooth Low Energy and you do not have a free USB port for the included Logi Bolt receiver.
Confirm the hand and the dimensions on the manufacturer page before you order.

FAQ
What connection does the MX Keys S page name?
The page says the keyboard connects by Bluetooth Low Energy or the included Logi Bolt receiver, and that it is not compatible with other Logitech USB receivers.
Is the Lift the same arm position as a flat mouse?
No. CCOHS describes forearms roughly parallel to the floor.
When should you skip both?
Skip them when your current keyboard fits the measured desk depth and your wrists already stay straight. A new shape does not fix a desk that is too high or too shallow.
