Yes, on balance I would say it is a success and the cars can race more closely without being affected by turbulence. Sure they are a bit clumsy, but it is what it is and there are reasons for that (discussed below).
You have to put the 18" tyres (+17kg, +1kg BBS vs OZ) aside from the other changes, as they (and that part of the extra weight) aren't part of the aerodynamic package to improve following.

- the size and weight do make cars look to sluggish.

The cars are just too heavy and large in my opinion.
The rest of the extra weight is mostly safety improvements (+20kg) and increase of cockpit size to help taller drivers, so that is non-negotiable. [I would welcome a return to V8 or V10 naturally aspirated engines to save over 70 kg (noting that power unit weight is also +1kg for 2022 to 151kg + 20kg battery) but I don't think that is going to happen!]
Without knowing the exact numbers, they have probably gone from a chassis (tub) weighing ~60kg 17-18 years ago, to ~99kg quoted by Caterham 7-8 years ago, to now weighing 120kg + 17kg halo (137kg) so that's a significant increase in safety and explains a lot of the weight increase (and from the car being underweight and running ballast, to now being overweight and not running ballast apart from the driver minimum weight ballast, driver weight itself also +5kg).
Complaining about wheelbase is futile as teams didn't agree to less than 3600mm (FIA wanted 3400mm of course), while 2000mm track width is if anything still too narrow and it should be the proper 2150mm [
2150mm example 1 ,
2150mm example 2]. Slightly longer control arms would make almost no difference to the weight of the car.
If we consider
just the aerodynamic side of the changes, the cars can certainly race more closely, much like F2 cars, so I would say job done. The midpack was 3 to 4 cars wide on the opening lap!
18" tyres is really a different topic and not part of the aerodynamic objectives IMO. Part of the stiffness is trying to control the ride height with less tools (a good thing IMO) and part of it is the 18" tyres. It is what is. F2 cars are also quite stiff and lift wheels around Casino hairpin.

If the cars were able to refuelled then they can be lighter, smaller and run in a more agile way. That isn't going to be reintroduced though.
If there is refuelling it should be gravity-fed like other racing series and not with the, IMO, overly dangerous pressurised system introduced by Gordon Murray. But I quite like that there is no refuelling.
