each round one second long, so on your turn you only have time to either move or act or do nothing. This does mean each turn feels really fast

I disagree. Apart from choice-paralysis (do I do nothing again or finally go now?), this approach can either be slow or fast.
If you slap into each action a bunch of modifiers, temporary modifiers, dice counting (large pools), reaction roll, detraction, comparison, etc that will in the end make that one game-second take ages in play time.

I don’t know what kind of reel do you reap but coming to fedi to advertise discord is rich

I expect this is going to be rather a short run instead of some long plotbook. So you probably could just take the story and wing the stats. I also don’t play OG Shadowrun
