I'm looking to purchase my first rental property and have been searching for a deal that would generate positive cash flow based on my projections.

I'm also seeing lots of homes for sale that were used as Airbnbs, so I'm wondering if that along with these numbers may indicate it's an overly saturated market, and if these are signs that maybe I should keep searching for a stronger market, or just a property that cash flows given the average annual revenue?

Is there something like off-market commercial deals where I can search them (like Investorlift or New Western for residential) ?

The easiest is doing a search for REI Meetups.

You can also use the search feature (magnifying glass in upper-right) to look at previous conversations.

There will not be one PM covering all the places you mention in your post, so maybe refine your search a little, and then you can start interviewing.

Use crime maps and local insights to guide your search.9.

You can also find real estate investing groups through meetup.com, Facebook, or a Google search.
