What to look for when buying GPON ONUs

I'm looking to buy an alternative CPE to the one that the GPON ISP provider rented, simply because it isn't completely on my company's control nor it is known for respecting the configurations inserted on its crappy web interface. The main issue is that it powers on randomly an embedded WiFi AP intended for home users that was explicitly turned off on the admin interface, polluting the spectrum and - considering the carelessness of the ISP - probably even has serious security issues.

Ideally I would just switch ISPs to one that cares just a little bit about security or something like that, but they're really the only ones that services this specific location: it's a remote site that's using a SOHO-grade uplink, as it is the only economically viable option. I'm well versed into LAN Ethernet and xDSL networks, but never had much opportunity to learn about GPON, or even WAN optical links for that matter.

If I plug the ISP fibre to something like an UFiber Nano GPON CPE, or the Mikrotik GPON ONU, things are supposed to just work (still having to terminate the PPP session at the router, obviously)? Or there's something like an embedded crypto key into the ISP-provided ONU that I probably won't be able to extract in order to decode the downstream? What should I be aware of?

The link itself it's a 300Mbps down/150Mbps up GPON link currently being terminated by a MitraStar GPT-2541GNAC-N2 box.
