Does a higher gauge electrical wire impact voltage level?

Throughout the day the voltage level varies from the power company. Not by much but it's from 110 to 123.

Does overall voltage level get impacted when higher gauge electrical wires are used from the breaker to the outlet?

Meaning, how much voltage drops on one end of a conductor compared to the other end, at the source. Voltage drop is proportional to current in this formula: V = I (current) * R (resistance) That's the formula, but I is in Amps. So, no current, no drop. If the voltage at an outlet with no other current on the circuit is going up and down then it's caused at the source. If the voltage goes up and down based on devices you turn on, then it's caused by wiring between you and the transformer. In this case, higher gauge wiring would have lower drop because R would be lower.

Resistance (R) measured in ohms increases as wire diameter decreases and gauge number gets higher.
