If you can find a 2x version with SRAM that would be my choice. Reason being is then you can do 1x with dropper actuated by left lever or 2x. Only problem with going 2x with SRAM is that you won't get a clutched rd but a Rival 1 RD is cheap nowadays. Another option is to go 46/36 crank with 11-42 cassette with a Rival 1 RD. That should provide enough range.
