Strain relief on wires is a very very good idea [tm] if soldering
directly to PCB.

Compromise:

Provide hole in PCB where wire is to be attached.
Thread wire through hole from other side to pad then solder.
This provides much better strain relief than having none at all.

Better:  Provide two holes. Thread wire from pade side through hole1,
back through hole 2 then solder. This provides good strain relief.

Thicker multi strand wires are less prone to falling off under duress
than thinner ones. More strands and/or thicker strands helps.
Do not use single strand / solid core wires for interconnection
(unless you are doing it for a very special reason and understand the
mechanical implications).
