This is a pretty interesting place to be. Since you have not yet committed yourself - so you sort of have a superpower that many of us crave for.

There are at least a few ways of thinking about this.

The well documented ones 1. Think about problems you've faced. Solve it. 2. Research online, find problems, fix them (what you seem to be doing).

Less Documented ones: 1. Pick a product you like - as a customer / user. Deep dive. See what they got right and what they didn't. Who they serve well, and who isn't happy. Then build something similar in a 'different' market (what Notion did to Evernote and Roam is doing to Notion, Freshdesk to Zendesk).

2. Think of 3-5 skills you've got as an individual. Forget products for a moment. Think about people - who can you help with a combination of those skills, better than most (or cheaper than most). Talk to these people. Offer your service. Later build a product around this (Close.com, and if I remember correctly, even Kissmetrics.)
