Know-How Exchange : Strategy

I am a one-person marketing team and am putting together my 2025 strategy that includes blogs, social media posts, website content, and newsletters. Is there a template or program someone has used where everything is in one place. I want to present to my partners the schedule of all marketing activities, including follow-ups and drip campaigns, that they can understand and view all at once. I currently use excel spreadsheets but was not sure if there was something else more sophisticated. Any help or suggestions is very much appreciated.
Please reach out to me if you need more information.
