It's also worth noting that if we use the 2 second delayed action, not only is the mirror locked up before exposure (reducung vibration) but also the exposure is locked, so at that point we can take our eye away from the viewfinder.

What for?
In practice, under wedding shoot conditions, hoods stay on and back caps are always used. In slower shooting where lenses are not changed much, front and back caps are always used.
I don't keep replacing the lens cap after every shot though, that would I think be overkill...

I used to use the 100mm on film but currently have the 77mm, but I am seriously thinking of selling that and buying the 70mm instead. It doesn't sound a lot of difference, but the shorter lens suits me slightly better and I would be back to the field of view of the 100mm lenses that I used to like very much.

Exposures of average subjects should be fine with matrix or centre weighted metering, but leave spot metering unbtil the camera is understood better.
Starting with images that don't contain lots of sky would be good, but also look at the way your subject is lit and make sure some light is actually falling on it, not coming from behind it. Photography is all about light.

I suspect a lot of the time though I will be using the 18-135mm, which I rather like.

On film, the 24-90mm was superb.

On the face of it, to have so long and exposure in light bright enough to cause a problem, seems like quite an extreme situation, so is this happening when very dark ND filters are being used?
Light leakage in cameras has always existed, but usually the exposure is so short it's not obvious and usually it affects the metering more than anything else. I would have expected the flipped up mirror to seal off any leakage from the prism area.
