what size should i pick if im using flashforge creator pro?

If you're building a dry box you want the 2 mm inner diameter to best fit the 1.75 mm filament. That's what I used when I built my dry box and it works great. If you're looking to replace the guide tubes that came with the printer, you'll need something wider, looks like mine is 8 mm outer diameter.

Can this be used for siphoning wine?

Very probable but I would think a bigger diameter tube would be better, and a cheaper option would be polythene tubing.

What about the replacement blades? Can I order more separately?

Sorry, we just sell tube cutter, blades are not sold separately
