I’m also wondering, when considering ones own frame of reference, would one always experience time to be the same (unchanging) regardless of their position or environment changing, and, would that also mean you wouldn’t notice space contracting or expanding either?

Space expansion doesn’t happen where you are. It happens between you and some distant point.

Reason being of course is that over smaller scales, gravity decouples us from the larger scale expansion rates, and on even smaller scales [such as planets, stars, you and me] the EMF's and strong and weak nuclear forces overcome expansion.

In general, no, they would not remain in sync. There is one value of r in a circular orbit where the kinematic and gravitational effects cancel. (and launching would disrupt any synchronization)

By launching do you mean the launching movement through space is what causes the desynchronisation?

The changing speed and gravitational potential would result in a continually changing frequency that would differ from the ground clock before it settled into the orbit where the frequencies are equal.
