I always just presume you're rolling the dice with kids in the cabin or nearby. I've had a rough ride in every class with kids. (Including my own.) Worst ever was EK F with a screaming baby in my cabin with his father and grandmother SIN-DXB for literally from push back in SIN to gate arrival in DXB. That was rough. I slept very very soundly on my second sector ex DXB.

I've gone back and forth on 35G mini-cabin. Ultimately I avoid it these days, because PEY and Y pax tend to pass thru the mini cabin to use the door R2 bathroom sometimes and there just isn't a whole lot crew often do about it. And I just don't like foot traffic. (For the same reason I personally wouldnt choose forward rows in front cabin.) It is true PEY bassinets are closeby too to mini-cabin. On a perfect flight I think it's better than the forward section but few flights are perfect. I choose last few rows in forward sections for long flights and seats 12A/K or 14 etc (near front) for shorthauls. I don't care about foot traffic for short flight and like being near the forward galley (where service comes from) and lavs. But longhauls I don't choose those seats.

Back when I was flying more CX A350s /3-class 777s and long-haul A333s (pre covid basically), I would sometimes ask upon checkin loading for j pey and/or y. And if it's an empty flight then I might move into mini cabin. But on full flight I prefer forward.
