Hands, feet, on the controls.
Procedures may be type specific, relating to the certification. e.g. the BAe 146 autopilot used 4 sec pilot reaction for non approach modes, thus hands-free; for coupled approaches(< 1000 ft), certification required hands-on to meet a 2 sec reaction time down to min use ht.
The Avro RJ with a different autoflight system did not have the same requirements - auto approach certified to Cat 3.
Some pilots liked to fly hands-on with autoflight to provided feel of aircraft control reactions and anticipate later manual take over.
For the take off scenario, any calls or change in control should consider likely time lags and how these relate to the assumptions in certificated performance; from memory the margins for a rejected takeoff are very low in comparison with other performance assumptions.
