Welcome to Smogon! Take a moment to read the Introduction to Smogon for a run-down on everything Smogon, and make sure you take some time to read the global rules.
yes (sorry, my game is in Spanish. first move is Scald. Escaldar = Scald in Spanish)
yea it's literally Calm Mind + Refresh in one move and yes it gets it
Chansey and Bliss don't get Wish anymore, that was a gen3 event move and transfers into gen 9 now delete whatever moves the transferred mon had. they can still be used in Stall but they can no longer Wishpass.
on my actual copy of the game (Violet), I'm gonna run all 3 starters so this is basically what I expect to bring:
on my..."early copy" of Scarlet, I ended up running with this:
which is not what I expected. I thought I was gonna use Pooper as my poison and and ground, run Pawmi for electric and...
you can still get Naganadel by the time you fight the Elite Four, though, since the Move Relearner is chilling at the Pokemon Center right before you enter the building to fight them.
you just need a Heart Scale (which you can farm at Route 9)

what everyone else said: in-game trade for a Spearow in the Pokemon Center of Route 3 but you can also catch them in Route 3, they're just harder to find than the other mons. and like everyone else said, Jynx is not version exclusive. Smoochum are pretty common in Seaward Cave which is by...

also, for in-game purposes, you won't be able to use Naganadel until you reach the Pokemon Center right before you battle the Elite Four since it can't learn Dragon Pulse anymore at the level you receive it (40). you'll need a Heart Scale in order to get one before the end of the campaign.
yea I don't have two 3DS's to test it out but we have always been able to trade and battle within the same generation. The only thing is that we can't trade or battle with anything that didn't exist in Sun and Moon.
btw I don't know if it's been said here (or if I even said it, I haven't got...
1-yes. you fight Necrozma twice before you're able to capture it. quite literally on your way up Mount Lanakila or however it's spelled. It's impossible to miss
2-gone. Zygarde 50% is now found in the Resolution Cave on Poni Island. the trailer on Ula'Ula that had the little mini Zygarde lab is...
