Looking at your list, they seem to be handy things that consumers could use to solve a problem that bothers them a little. What you want is a product that fixes the immediate existential threat that an otherwise wildly successful company just discovered they have (ideally as a result of reading the copy on your homepage.)
I made a list of things my next SaaS product should have. No particular order, but give yourself a point for each one you can tick:
- Business: Purchased by businesses as opposed to consumers
- Aspirin: More like aspirin (takes an existing pain away) than a vitamin (nice to have)
- Valuable: Immediately saves >$100/month by using it
- 50x500: Market to quickly sell 500 subscriptions at $50/month
- Paid: Paid from day one as opposed to Freemium
- Recurring: Continues providing value every month, not just one time or occasionally
- Immediate: Useful straight away by user #1
- Network: More useful the more users in the Org use it
- Supportable: Low instance of customer support. Few emails asking for help
- Fun: Interesting enough to keep working on
- Buildable: Not to huge in scope. Can be built as MVP, then iterated
List out your ideas, add up the number of boxes they tick, and that's your score. I've had a lot of ideas for a lot of things I wanted to build, but thus far none that score more than 10.
My existing products get a 6 and 7 respectively, and they still bring in enough to live comfortably, so it's certainly possible to succeed without all those bits above. But if you can meet most of those requirements, you'll find yourself on a much easier road.
Good luck!
