A family member's house was completely rewired in 2011 and has arc-fault
breakers for the bedrooms. One of those breakers will not hold in at
all, even with nothing plugged into any of the outlets.

Is substituting a replacement breaker the most appropriate first step,
or is there something else to try first?

# 1 before disconnecting anything check for Voltage between
Neutral and Ground, there should "NOT" be any voltage,
then check Voltage between Hot and Ground which it should be same
as: between hot and neutral, if either one is off you got wiring problem,
get the people who did original wiring to corrected.
The receptacle should have silver screw for neutral white wire.
and bras for hot black wire,
Do "NOT" switch this two.
