Getting your tooling to cooperate is a huge part of being able to get work done during a jam. Our team stumbled upon a tool called Super Tiled2Unity that takes advantage of the recently-added Scripted Imports in Unity. It's fairly new, and I wrote up an article about our experience on our game's itch.io page that covers how we dealt with Tiled maps, collisions, object properties, and more.

I would have posted the original here, but the formatting on itch.io doesn't translate all that well.
