ᐅ Unifi NanoHD on a Concrete Ceiling – What Type of Junction Box Should Be Used?

Hello everyone,
I’m wondering what type of mounting box would be best to install in a precast concrete ceiling to easily mount a Wi-Fi access point (the plan is to use a Unifi NanoHD, or possibly the already available Access Point AC Pro for now) without a suspended ceiling.
The architect suggests a HaloX 180, but that seems a bit excessive to me. Especially if, at least in the longer term, the NanoHD is going to be mounted on the ceiling. It only has a diameter of 16cm (6.3 inches) and therefore might not fully cover the HaloX or its mineral fiber panel.
Is it possible to install a standard flush-mounted box in such a precast concrete ceiling (apparently from Dennert, if that’s relevant)? I imagine it could be used to house the CAT cable, keystone jack, and a short patch cable, with the access point then installed on top. Would there be enough space for that?
Are there any better solutions?
Thanks in advance!

I would simply use a hollow wall box...
Place and secure it from above (before pouring the concrete) onto the precast floor slab. Then drill through the bottom of the box and the precast slab using a 12mm (0.47 inch) drill bit. This way, you can leave a cable hanging below (a 20cm (8 inch) patch cable with a keystone connector attached to the installation cable) and push it back into the box as far as needed. The diameter of the access point has nothing to do with the box... The box serves purely as a cable conduit.

Place it on the prefabricated concrete slab from above (before pouring the concrete) and secure it. Then drill through the bottom of the box and the slab (using a 12mm (½ inch) drill bit). This way, you can hang a cable out at the bottom (a 20cm (8 inch) patch cable with a keystone attached to the in-wall cable) and push it back into the box as far as needed. The diameter of the access point has nothing to do with the box... The box acts purely as a cable sleeve.That sounds like the solution I’ve been looking for (at least as a layperson), thank you very much!
Sorry if this is a silly question: Could you maybe tell me which type of cavity box would be suitable for this?
I didn’t install a junction box but only pulled a conduit. That works too, but I would recommend a small junction box. The connector plug was quite fiddly to handle. And I had purposely bought a very short one.
Whether the mineral wool board is larger doesn’t really matter. You won’t leave the ceiling unfinished but will plaster or do something similar.

I didn’t install a junction box at all; I only pulled a conduit. What diameter did you use there? I’m worried that I won’t be able to push the Keystone module back through the conduit...
