Also, would there need to be any changes to the gas system between running super or subsonic ammunition, can or no can?

In my experience, no. Not at all.
10.5" 300blk. I do run suppressed, but don't have to.
I didn't do anything differently than any other build I've done. Standard lo-pro gas block, standard BCG, and a Geissele Super42 with H2 buffer. Runs like a clock with supers, subs, suppressed, unsuppressed, or any combo thereof.
Don't overthink it. The cartridge is designed for what you're doing. Put it together and shoot it!
Also, hurry up with the can
. 300blk is intended for supressed shooting
