My garage is cinder block. I'm installing two outdoor motion sensor
decorated accent lights on each side of my garage door. I'm mounting the
fixture directly to the block, drilling a hole through the block and
running Romex through to the inside of the garage, which will then
continue the run into the breaker panel. When running the Romex through
the cinder block from the fixture on the outside to the inside, I am
planning to insert a piece of conduit or PVC in the drilled hole, then
running Romex through it. Is this the best option to run the wire to panel?

Thanks
It is legal to fish romex directly through the cores of concrete
block. The issue is when it comes out. Exposed sections need to be
protected from damage

What about using UF to go through a concrete wall? That's what I did when I couldn't use a sleeve. When I used a sleeve, I used 1/2 PVC conduit and silicone sealant around it then ran the Romex through the sleeve to the fixture. I didn't check code, I just used common sense and considered ways the standard Romex might be damaged or get wet. Any fixture always got a bead of sealant in a U shape, open at the bottom so any water could drip out. (€¢€¿€¢)
