If the battery side + of a controller is interrupted by a bat cutoff switch between the controller and the battery, are there any major problems with such a setup when turning the cutoff on and off during normal use.
Flipping the cutoff on and off is not what II would call a "normal use". Normal wiring would be controller to battery via its own breaker. Not directly to battery, and not via general cutoff switch.
Same for loads - they should be connected to battery via "loads" breaker.
Then you can disconnect either loads or controller or both, if needed. Disconnecting loads is what you do in storage, - this is better than battery disconnect because you stop battery drain but keep controller running, maintaining the battery. Or flip controller breaker if you absolutely have to - and then it should be the FIRST thing to do.
In my trailer the only "battery disconnect" is a battery fuse, mounted on the battery Pos terminal. From there, Pos goes to Pos buss, and from there - to the aforesaid loads breaker and controller breaker. I bypassed the general trailer fuse under the frame - too darn inconvenient. Serious guys have a proper battery switch by Blue Sea, besides the battery fuse. I've been postponing this for years 'cause don't see what exactly it will give me.
