Speaking as someone who reads a lot of resumes, my advice is to use space wisely, focus on what exactly you did (too many resumes talk about the team or company) and why you're awesome, and (whenever possible) tailor your resume for each job to prioritize what matches the job description. Also, while I understand the point of the one-pager, with the massive number of applications I see, a one-pager that's light on relevant info is going to get passed over in favor of a longer resume that highlights germane skills ans experiences.
