LED bulb question
I had an electrician fix this fixture as there was a loose wire and it flickered constantly.
.
Now, when turning the fixture off the bulb can have a delayed glow before shutting off entirely. It’s an LED bulb. Did the electrician miss something or is that normal for an LED bulb?

Depending on the bulb..... it can be normal for the light to remain on dim or even flicker when the switch is turned off. LED's are very sensitive to low voltages and can work with what's called ghost voltages. That's when the switched power power to the light is in close proximity to an always live wire.
Manufacturers are now adding snubber resistors inside the bulb to help them shut off fully.

I have several bulbs that will delay in turning off and if I look closely they still have a very dim glow even after I thought they were off.

Agreed this is normal. The capacitors in them tend to cause a fade out effect. It depends on the brand how noticeable it is... but definitely not something mis-wired or out of the ordinary.
All the flood lights at Home Depot seem to be designed for a junction box that is flush to the wall, such that the light's junction box cover sits against the wall. For example, this light
If I use these, they should overlap the junction box, but I guess water will be able to get in from behind unless the overlap is very small and I can seal it with silicone caulk. If I could get it sealed, in terms of color matching, I could spray the light fixture parts with silver spray paint. From a distance, that would look good enough.
Other options?
