For general fitness training, what are the pros and cons of a heavier commuter bike vs lightweight more aerodynamic bike?
Making the work out more enjoyable as you can travel further.Also, it is differnt training. A heavier bike on shorter rides will be a different trainging sessions to a longer ride on a better bike.

The first mistake you are making is confusing fitness training with strength training. Cycling is about fitness, not strength.

Fair enough, maybe I should change to 'physical' training, covering anything

In fitness terms only, I would suspect that the aero bike will improve your core significantly more than the commuter. Other than that, it is all down the effort you put in and how long you can last on each bike.

There are no 'benefits' to riding a heavier bike. Regardless of the weight of the bike, the rider will pedal it at an optimum rate according to their fitness level.

What's the reason for that do you think?

The position you need to be able to get into and then hold. An aero bike will have you much lower requiring you to either improve your core or take the weight on your hands (not a great idea).

People in groups of varying abilities?

If people have differing fitness levels, then they have differing fitness levels. If one rider needs to ride at full CV in order to stay with another rider riding significantly sub threshold, then that is never going to end well. Not sure what you are asking?

The quote "It never gets easier, you just go faster." (Greg LeMond) could be applied to this (lighter/aero frame versus 'heavier commuter' - but he was referring to being fitter, I think). (To which one could add 'or further'.)
And might I add to @Citius 's one liner above: ". . . according to their fitness level and inclination." I guess you will get some people who enjoy a nice heavy bike and work harder as a result. Also if going out in a group which they think is likely to be on average of lower fitness than they believe themselves to be, a rider might select her/his heavier bike as she/he'll get a good ride (ie plenty of effort) while staying with the group (as opposed to getting cold waiting at the top of each climb).

Highlighting just one reason why a heavier bike would be of no benefit.

Define 'heavier'. Unless the bike is several times the weight of the 'lighter' bike, there will be practically no difference on the flat (thanks to Newton's laws of motion and the conservation of momentum), and only minor, largely undetectable differences when climbing.

Joining in with your defining spirit, define:
minor, largely undetectable differences
A bike 2kg heavier would be 2% (ish - please forgive me for not re-examining the formula) harder (power at the same speed) to cycle up a hill.
I reckon if I'd had 2% more on the critical climb yesterday morning (club run), I wouldn't have been dropped. (NB I did not 'choose' to ride my heavier bike, btw.)

And that's not because they necessarily think that heavier bikes are better for their 'fitness' it's because they are both (Ferrand-Prévot and Vos) superb XC and MTB champions and have enjoyed success in those disciplines since youth.
No, not because they're heavier bikes (and I never said it was) but it is good for fitness because even the mighty Vos thinks she'd struggle to keep motivated plugging away with the same bike all year long: "each has different variations of training, different races and different people, so I don’t get bored by doing the same thing. Mixing my disciplines helps me to stay focused the whole year and they help me to become a more complete rider." in a road.cc interview

Except in high winds, you don't enjoy the weight as such, but more that you're not sat on a razor blade exposed to the water, mud and oil due to no mudguards or chainguard and that heavy bikes can have all mod cons like better navigation aids, food and drink set out in front of you, a sound system, hot coffee, heated gloves and overshoes, perpetual lights, a sofa... (and yes, I've seen all those and more... although the sofacycle is getting up there with the pub bike as specialist kit, really).
