Might want to check out keychron.

A lot of mice list the switches they’re using, so you can just google it and see what its sound profile is like. Anything with a sensor from the past 6 years will perform the same, so just pick whatever you like the most based on shape and color.

Take a look at the mountain makalu!! I absolutely love it. And its light and fits right in my hand. Kind of hard to find except on ebay. Very solid mouse to replace my a310 steelseries.

I've been pretty happy with my Glorious Model D wired, feels good as far as shape and button quality, tracks nicely and works great in games. The switches are a little clicky like most mice, but looking at the construction it looks quite easy to open up to solder new ones in.

It works with OpenRGB too.

OP1 looks great according to RTings, here it is compared to your CM MM720 with plenty of data and informations.

Maybe checkout Incott G23. It has hotswappable optical switches. It came with a couple of extra switches when I bought it and one of the pairs were silent. It works both wired and wireless.

Their web driver works on Brave Browser for me on linux (I think I remember adding a udev rule for this). I'm guessing it only works on chromium browsers since they say it only works on chrome and edge on their page.
