Raw conversion to jpeg dpi setting

Hello, I am currently taking all my photos in RAW then editing and converting to Jpg for submission to Adobe. I looked through some forums and found most people suggesting 300 dpi for conversion output setting, but my scanner has a 600dpi option so for this format do I want to go with a higher dpi setting? All of the posts I've found were mainly talking about converting the photos for printing, but as these will be submissions for Adobe Stock then manipulated later by potential customers do I want to go higher than 300 dpi? I want the submissions to be the best they can be and have always been a fan of overkill. Is there a suggested dpi from Adobe that i haven't found yet? Do i want to go higher than 300 dpi if it's an available option? And if so, what would be an good setting? Thank you for your time. Have a good day.
