Still no problem with my D750.

Select Mup (mirror up) - select.

No electronic shutter. See note below.

Wireless shutter release - check

Focus peaking (of a kind) - check.
See https://www.dpreview.com/forums/post/57292217

Heavy! Vibrate it if you can - check.

Note: I'm not keen on electronic shutters. They can lead to image
distortion with action shots and they are reputed to shorten the life
of the sensor.
