If you don’t have a decent cleaning rod, I love these proshot rods, I probably have a half dozen of them now. I leave a rod with jag on it and rod with a brush on it for the calibers I shoot most so I can clean faster (yeah, first world difficulties).

Get good quality patches too, they make a difference. I use proshot patches as well.
Your gun will be a Gen3 and does have an accessory rail (only Gen Glock can sell in Cali).
You’ll likely want to change the sites at some point but what you think you want on a gun and what you will want will change as you get experience. The factory sights aren’t as bad as folks try to make them out to be. Shoot the gun for awhile and you’ll have a better idea what you want.
One thought, with ammo as scarce as it is, picking up some dummy rounds or a snap cap would be a good idea for dry fire practice.
