The only switch type with a mechanism designed to generate noise (in modern switches) are the Cherry MX Blues. Black, Brown, Clear, Red all lack this. Black and Red are linear switches with no tactile point to tell when actuation occurs (though it is always at 2mm of travel) while Clear and Brown both have a tactile point where the force graph changes a touch to let you know you've hit that point.
Blacks are generally the hardest to bottom out due to the force increasing from 40g to 80g (actuation at 60g) linearly with travel, while Browns have actuation at 40g (I believe) and Reds are at 35g.
Membrane keyboards are roughly 55 to 60g of force at ~4mm of travel, with margins because of how the rubber moves under compression. Logitech keyboards, especially their G series, tend to be extremely mushy feeling with very little feedback till you've bottomed out. And even then, its vague. In my opinion, old Dell keyboards that you can find in surplus anywhere have a more consistent and progressive feel to them, and I've had several friends I know sell their G series board because they felt the 2 dollar Dell I got from a thrift store felt better.
The display on the G series keyboards is, in my opinion, the same as having an air fuel meter in a Civic with an intake - it is just there to look cool but really doesn't add much. You can get email notifications on damn near any phone these days, and if you are honestly that worried about your core temp I believe you have other things to worry about.
Also, if you (Greyfox) think that all mechanical keyboards are clicky, you've very clearly spent no time actually dealing with them. Black switches are quite easy to test, as they are a popular option for gaming keyboards. Razer also has Blue and Brown switched keyboards for very fair prices (cheaper than the G series boards) that are infinitely better for anything where you actually care about the typing experience.
