Network socket for access point for indoor and outdoor use

Hello everyone,
I am currently doing my network planning. Among other things, I want to install access points indoors (ceiling) as well as outdoors (wall).
Of course, I do not want any cables from the access point to a socket to be visible, i.e., the network socket should disappear behind the access point.

Indoors, I have planned it as follows:
Run cable into a hollow wall box in the ceiling. Connect a keystone module there and install the access point directly on it with a short patch cable.
Advantage: The access point sits flush with the ceiling. In the worst case, you could put a cover on it.

Outdoors, I actually intended to do the same. I just wonder if you are allowed to use keystone modules like this here?
I have also found various "IP68 socket housings for keystone modules" on the internet. But I would have to somehow screw them into a box outdoors.

Or are there better solutions for this (indoors and outdoors)?

Regards
Chris

Indoor area sounds good. We planned to hang the access point on a wall, but now it is lying under the couch in the living room (assuming [Bodendose]).

For outside: Possibly just make one hole (or lay a patch cable into the wall) so that the patch cable can be passed through without a connector. Then inside use the solution with a cavity box and keystone or directly connect installation cable with patch cable using a "CAT 6 Cable extender," and outside crimp the patch cable itself with a connector. Then you would have a cable with a connector available directly outside for connection.
