You really need to show an AI version of what each of these combinations looks like on your home. People don't have time to look up each siding with each trim color.

Also, are you leaving your brick natural OR are you having it painted or covered?

Is your roof light gray or light brown?

4 of those colors will be indistinguishable from each other installed exterior.

Pick one of the 4 in the pink box that works best, harmonizes best with the brick.

Compare that Color to Wish and Anew Gray.

Be aware that Wish can show up purple-ish. And, no, that does not mean it that it will, or that has "purple undertones". Undertones are not facts. Just look for moments of purple when comparing.

Pick the one that works best with the brick.

White Dove is the only trim color that will show up looking noticeably different from the siding color.

Shoji works with Anew but the contrast between the two will be still be minimal.

Are you getting new garage doors? Because they will be much more noticeable in walnut than they are now, and I'm not sure you would want them to be the focal point of your front yard. It might be better to keep them the same color as the body of the house so that they recede visually. As Lori Sawaya says, I would choose whichever gray matches the brick best. But I would also go for a trim color that is fairly close to the siding color, because otherwise you risk the house looking too chopped up and busy, and losing the calm elegance that it has now. I would also go for replacing the three lights on the garage (I can't quite see what is on the porch) with something larger, more in scale with the size of the house.

I tried the Sherwin-Williams Visualizer with the combos you suggested. IMO: dullsville. Here's #1 (the visualizer doesn't let you "paint" the garage door, a third color has to be the door and shutters). You can upload your own photo.

There’s a fair amount of pretty busy brick on the front in my opinion there isn’t any visual bandwidth to get cute with color and in this case boring won’t be boring

I think it looks nice the way it is. I like the fact that the trim isn't white, and doesn't "pop." It looks more cohesive when the trim and the siding are the same color.

these colors would be lovely with your light brick,

BM Boothbay Gray for siding and SW Misty for trim(s)

the woodtone garage doors would be great.

still traditional, but softer, and not gray or beige.
