I haven't dealt with the issue yet, but I think I'd use the druid wildshape tables in Xanathar's. They list beasts by terrain type and CR.
So I'd look at the appropriate terrain table and pick the closest CR available. If there's more than 1 beast with the same CR, I'd randomly determing which beast is picked.
