As I think more about it, is it a better idea to paint the pieces w/SEM trim black as needed and forego any dressing-type products? Is that the preferred method of keeping the black pieces nice & black?
Any good rubber dressing should suffice. Some will last longer than others but stay away from the stuff that dries glossy and last for weeks. (I think Armor All makes it) It does last but it also gets crusty and cakes up with repeated use. The stuff I use is not available commercially but it's not hard to come by. Most all reconditioning supply dealers sell their own brand of dressing, usually silicone and solvent based with a blue color and a sweet smell to it. If you intend on keeping the rubber weather seals dressed make sure it will not affect the rubber long term....some dressings can actually accelerate rubber breakdown.
I would only paint as a last resort. Once it's painted you can't go back. If your pieces are in good shape then just keep them dressed every so often.

On my car, I only ever use Diversey Inc.'s Deep Gloss Stainless Steel Maintainer on the black plastic exterior trim pieces. I know, sounds weird, but it does the trick for me. Spray a liberal amount onto a paper towel and apply heavily to the trim pieces. Allow to somewhat dry, and then wipe off excess with a fresh paper towel. Done. I do it every time I wipe down the stainless with the same product, which is probably once a week when driving.

It leaves a nice natural black appearance (not overly dark) and an ever so slight glossy finish (but nothing extreme).
I'd avoid any of the silicone based products, as even though they'll make the pieces look nice and black (and IMHO, almost artificially black) for a short while, they'll also cause significantly faster dry out / fade unless you're constantly reapplying them.
Keep it simple, keep it cheap - that's my motto

If you can find it, Black Again is the stuff to use. It lasts and will make all of the exterior black plastic and rubber surfaces look like new. From the rear sunshade to the grills behind the doors, the side rub rail, and the bumpers. The rear view mirrors, the door sills, everywhere. Yes, if you do intend to paint any of this it is difficult to remove so you do not contaminate the paint.

It's a water based product, so using it won't affect subsequent paint-ability, should you decide to go that route.
As for the door seals, I use 303 Aerospace Protectant, when I treat the vinyl with the same product, roughly twice every year. Good stuff.

Meguire's Natural Shine is good. Lasts about a year between reapplications and a little goes a long way.
Black Again is OK, too.
No Armor All!!
Try to keep the application as thin, yet even, as you can. Wipe off any excess. Twice. Too shiny otherwise. Especially on the fascias. Keep it off the SS.
Good for the side vents, the louver/sunshade, the lower rocker panels, the spoiler, the lower quarter panel trim behind the rear wheels and the side rub strips. Also good for the unpainted (original black) sections of the fascias. A bit time-consuming to get the excess out from the corners of the embossed lettering in the rear fascia. But worth it.

I recently painted my mirrors, door vents, and license plate bezel with SEM trim black and they look fantastic! Use a scouring pad that they sell at most automotive paint stores to scuff up the plastic (but lightly so as not to remove the texture), then apply adhesion promotor and SEM trim black. I'm doing the engine cover, sunshade, rubber bumper strips, and windshield trim next. The bumpers and grill are not suppose to be painted as I understand.
