Don't use installation "indoor". Use installation "any" if it is indoors. This will include the outdoor allowed frequencies
Mikrotik misunderstood the rules. There are no "outdoor only" frequencies, there are "indoor only" and "also allowed outdoor" frequencies. You are free to use the frequencies labeled "outdoor" in the Mikrotik list if operating indoors. There is no risk of breaking the rules.

By the way , if you choose XXXX you have lost control. 5240XXXX could be any of the Ce combinations, could be the intended 5240/eeeC, but 5240/Ceee as well (channel 48-60).
Don't be afraid of DFS, just allow it one full minute to start. Just stay away from the weather channels unless you have a lot of patience (10 minutes wait time).
With DFS you do set the channel manually, don't set it on auto. The DFS channel mandatory switch by radar detect will still work. If you want to avoid the weather channels, fill in the Channels List with the channels you allow, in your preferred sequence. Operating indoor, the chances of receiving a radar detect are minimal.
Why not auto? Because the auto selection happens at startup, and Mikrotik and other brands make very very bad choices if set on auto. They introduce adjacent channel interference, which could be avoided, or even transformed to the better co-channel interference (coexistence). They prefer to corrupt the wifi spectrum with adjacent-channel interference, and mostly have it wrong because for a split second, while they test, there was no signal on that frequency. Channel selection must be based on a longer period of evaluation.
