I usually use Amsoil (where applicable) and their recommendation for both engines is 0W-20 (Signature).

Subaru specifies 0W-20, but I've heard that these engines can experience fuel contamination and high oil consumption. The particular vehicle has around 45k kms and is not using oil.

Honda specifies 0W-20. This vehicle has around 50k kms and is not using any oil.

Both vehicles are driven in the Vancouver, BC area. Typical lowest temperature is around -10C. Typical highest temperature is around 35C.

Should I go with 0W-20 or can I use 0W-30? Ideally, I would like to use the same oil in both.

You’ve got a good handle. Maybe use the 0w30 in summer and 0w20 in winter.
 
If these late model cars are running properly, the outside temperature makes absolutely no difference that would drive choice of oil. Honda's specify 0W20 and run hundreds of thousands of miles with that. Subarus have some engine issues, but certainly will work fine. Choose your in-spec 0W20 oil and go with that.
 
I'm in the same boat right now with my 21 outback 2.5. I've run Amsoil OE 3k and signature 5k OCI 0w20 with good results but both end up on the lower end for 20 weight viscosity. I'm definitely moving to a year round 0w-30 oil. Currently thinking of either going Amsoil Signature or Penzoil Euro 0w-30.
 
I ended up ordering 0W-20 for both vehicles. The Crosstrek is using approximately 1L / 3000 km, which is more than I would like, so I'm considering a higher viscosity.

According to the owner's manual, if 0W-20 is not available, it's allowable to use 5W-30 temporarily:
If 0W-20 synthetic oil is not available, 5W-30 conventional oil may be used if replenishment is needed but should be changed to 0W-20 synthetic oil at the next oil change.

Would it be better to use 0W-30 or 5W-30?

Won't matter. Quality and approvals would decide.

M1 ESP 0W30 better then 5W30 Supertech for example.

I’ve been running M1 AFE on my 21 Outback 2.5L and it burns zero oil and is clean as a whistle inside. 3 oil changes so far.
