I couldn't find anything specific or obvious but i'm curious if anyone can provide some info about this.

I just bought the RB3011UiAS-RM router and i have a C4948 with twin 10GB uplink modules. The issue i'm trying to find and verify is if the S+31DLC10D SFP module would work at 10GB speeds with the router i purchased.

I'd have to get SC to LC fiber but that's not a biggie. More so asking if anyone has used a 10GB SFP with this router model and if so what was the SFP model so i can get one that will work properly.

S+31DLC10D will work in RB3011UiAS-RM, but only at 1Gbps rate, because RB3011 only has SFP cage, that means modules inserted into it, can't work at 10Gbps. If you don't have the modules yet, I would recommend getting regular SFP modules, not SFP+.
Modules in table below are tested to work with RB3011, but there are no vendor locks on the device, so the list isn't exclusive.

Bummer, no worries. Thanks for the compatibility link!

I'm not sure if anyone can verify or has tried but do the Cisco 1GB SFP's work with MikroTik routers? I've got a couple laying around at my parents i was thinking of having them ship me.

Cisco GLC-SX-MM work absolutely fine. I picked a load up really cheap on the off chance and they work super. I can confirm even on the RB3011.
There is an alternative vendor SFO compatibility isn’t somewhere in the Wiki as well.
