I've been asked by a third-party partner to set up OFTP2 so they can send EDI files to us. I'm looking for recommendations on the best software options that are either open-source or cost-effective, as I'm having trouble finding useful resources without spending a lot of time researching. They will set up the connection to our Windows server, so I mainly need something that facilitates this connection effectively.

We're using OS4X Core, and honestly, it's been rock solid. We had an issue with our OFTP certificate expiring, which hadn't happened in eight years, and the support team helped us out pretty fast, providing a new certificate and guidance on updating.
Are you going to need ENGDAT and ENGPART support? If not, you might want to check out OdetteMC, which worked well for me in the past. Also, if it’s only a couple of partners you’re dealing with, a managed service might be a better fit. Look into Seeburger or Hüngsberg for options.
I maintain a setup using rvsEVO and it seems pretty reliable for my needs. You can find more about it on their official site. Might be worth considering if you want something stable and set up quickly.
OFTP2 is standardized under RFC 5024 from 2007, primarily for European use. There’s an open-source implementation in Java called Mendelson OFTP2. If you're interested in something minimal, check out the Go-based project, which is client-only. It might be good for testing.

I don't think I need ENGDAT or ENGPART right now, but I'll definitely take a look at those options, thanks!
