Please tell me which run I should watch.

I'd say to watch some top runs and runs under 30 mins to see the different strats/movements used by peoples, then try to reproduce that at your own and see how you're comfortable to use this or that strat/movement.

Also if you begin with runs, go for 5-2 instead of 5-3. Way much easier even if it loses a bit of time vs 5-3.

And you can also join our discord if you want to ask some questions to players running this game, they'll be happy to answer you: https://discord.gg/XfGPJmp

Ok, Thanks!
