What is your threat model? If you don’t want to give any data to these companies you simply can’t interact with them at all. Where do you draw the line? Once you have figured that out you can come up with a plan.
One thing you probably should always do is separating your business devices from your personal devices. Then create the accounts you need for your business and only use them with your work laptop or phone. If you want, you can invent a sockpuppet persona that acts as your social media manager. This should insulate your personal life from most tracking as long as you don’t use your work laptop for things unrelated to work. I wouldn’t fuss around too much with privacy preserving apps for a business accounts outside of ad-blocking and regularly cleaning up cookies.
