I should say all of the /smaller/ ones use a DC barrel connector and/or PoE.
Here's a DC model....but with fewer ports:

I have not opened up a CRS 317, but the AC powered CCR's all have a 24v
power supply inside the case. What I've been doing is cut the 24v
cable, drill a hole in the case, and bring it my own DC supply cable
from a meanwell RSD connected to the -48V plant. I wish they just
offered a DC version, but for the money saved I don't mind drilling one
hole and splicing two wires together.

Am I just missing something? when I look at one, i.e
https://mikrotik.com/product/crs317_1g_16s_rm it says dual AC inputs.
is there another version with DC?

Do the planet switches double tag (QinQ)? Have a
similar requirement to replace Ignite switches but they have to
support DC power, preferably -48. Looked at the mikrotik switches
but none but the little 6 port support DC!

It's hard to argue with those Mikrotik CRS switches for
what you get for the money, but I have my complaints.
I'd like to explore other switches with:
* at least 4 SFP+ ports
* at least 4 SFP ports
* DC input
* Extended temperature range (doesn't have to be -40,
but does need to operate below freezing)
* Smallish size (1/4 depth 1U, or possibly DIN rail)
I have feature wishes too, but just the size and
temperature spec takes 99% of switches out of the mix.
What options are there? I looked at an Adtran Netvanta
and loved it.....but the price tag will knock you out of
your chair. Rather than talk to every switch vendor in
the world, I wonder if any of you guys already found
something you like.
