I know people killing it in Dayton but I'd recommend looking at other strategies like buying land and building single and multifamily in columbus. you can get lots right now for 30k or 40k within 1 mile of downtown in Franklinton, king Lincoln, olde towne east, southern orchards. land is a buyer's market and low competition.

Your best bet to find cash flowing deals are either off market, or a BRRRR strategy. 

What 1 strategy should I hammer down and get good at ?

In this environment I wouldn't put all my eggs in the STR basket.If your insentent on this then you must put a lot of effort into vetting the area, the rules, the property etc to make absolutely sure a given property will cashflow with conservative numbers and what your exit strategy per property is if they don't go as anticipated.

Heck.. even @Bill Brandt brought up an 'investment strategy', j/k... but it's solid advice.

I chose not to buy a cabin for my first purchase so that I could have a couple exit strategies just in case so I'm ok with how things have turned out so far.

For sure I always wanted to try it out, and see if I can grow using this strategy. 

It offers practical advice, diverse market insights, and inspiring stories through interviews with successful investors, in-depth discussions on various investment strategies, and listener coaching calls.

It's really critical that you work with someone who understands investing and the strategies you're trying to deploy.

Also not focused on, no money down strategies if it all.
