No safety keep it in a tight holster at all times until you need it or clean it. One less thing to slow you down under stress you will have enough garbage going through your brain without wondering if the safety is on or off. That is what makes a revolver a good choice the simplicity of it.
To a thumb trained on a 1911 not having an on/off switch is a confusing issue with handguns. I've actually found my thumb searching for one on a revolver before.
Just goes to say whatever you choose for a primary and train hard on will become muscle memory.
To the original question. Choose what makes you comfortable but remember that muscle memory thing. After however long carrying without you might have a no bang situation if under stress and old point and shoot habits take over.
JMO but what limited handling of the 365 I've had I'd say if it ain't broke don't try to fix it. The 365 does not seem to have such a light trigger, more akin to a double action pull, to be overly concerned. Particularly if your reholster habits include clearance of clothing or obstruction.
But if you're wanting single action every shot as only carrying cocked and locked provides a on/off switch is a must. And in this case the switch must have a definitive and properly stiff on off function, something often overlooked in the aftermarket or add on design, because that is all that is standing in the way of light trigger bang. If memory serves the 365 safety positively clicks but isn't as heavy as my preference on a 1911.
If wanting the same double first pull a switch is nothing more than redundancy, which isn't a bad thing.
