I understand you are excited to come up with your own business online and sensing your drive to sell is very inspiring! :) In addition to the inputs here, building up your business is a beautiful process of learning. You, as the overall director, has all the say in it. In choosing the right product to sell, you can either check which are the in demand products now or
you can go for products you are mostly interested at.
If you go for the in demand products, of course, there would be more competition as current sellers are most likely selling it already. So, you can go find a good supplier for you to compete with the current marketplace. Or, you can also find a niche for that particular product so you can have your own market share.
If you go for products of your interest then, you can shorten the research and development process since you yourself is already a market of your product and you would know firsthand how to capture your market. And you will have stock knowledge and experience already with the product as it is of your liking. The major step here is to find the right supplier for you.
