I own couple of single home rentals in Tampa Florida and have always wanted to transition from long term to short term rentals.

I am today years old in terms of this forum and it's already provided a wealth of super useful information.

I suspect it will not be popular long.

As I get into short-term rentals, I’m curious: What should I look for when picking a location?

Long term friendships with local realtors How did you finance this deal?

Am thinking of converting a long term rental to a medium rental. 

At this time, the types of properties that I'm interested in pursuing are primarily multi-unit rentals and short term AirBnB properties.

Well, history shows what happened both in terms of marginal tenants ultimately getting hurt (as did many landlords) and the Supreme Court ruling the Eviction Moratorium as unconstitutional.I see the whole idea of rent control, which is just another form of government invasion for political hopes, being bad for everyone. 

I will say to forget your idea that you're going to build 10M in real estate just like that - it's a long term game and you have to be okay with a 10-year plan.

Everything here is a trade off and if you're interested in long term planning, it's best to ensure you fully understand how it all works before jumping in.
