Which one do I have to buy for 1x11, crank 30T and 11-46T rear?

I have this rear derailleur set up as a 1x11 with an 11-42 cassette, but I believe it can handle an 11-46. Check the specs on it on Shimano website.

Does it work for 9 speed x 3?

No, this is for an 11 speed setup. Best used as a 1x setup. One front chainring and an 11 speed cassette.

Is there no way to choose between the two sizes, thumbs down?

I have no idea why they put "one size" as an option lol. As long as you do not have more than 46t on the cassette, just close your eyes and pick one, it will work.

11x42(46) speed rear cassette. Which derailleur GS or SGS 2x 36/22 Ft crank. I read 2x11 SG but does not say which max tooth cassette it will handle.

Just installed 1X (30 chainring) with 46 rear 11 speed. Works great, 117 links.
